Provisioning Profile Does Not Include Required Speech Recognition Entitlement
I am building an iOS app with the App ID: com.echo.eyes.app I have a paid Apple Developer membership and have followed all correct procedures, including: Adding com.apple.developer.speech-recognition manually to the App.entitlements file Setting Info.plist keys for microphone and speech permissions Assigning my Apple Developer Team to the project Setting App/App.entitlements under Code Signing Entitlements Despite all this, Xcode automatic signing fails, and I receive the error: vbnet Copy Edit Provisioning profile 'iOS Team Provisioning Profile: com.echo.eyes.app' doesn't include the com.apple.developer.speech-recognition entitlement. I am unable to add the entitlement via the Capabilities section, and no method I try will allow provisioning to succeed. Please update this App ID to include the required entitlement in the provisioning profile. This issue is preventing all voice recognition functionality. Thank you.

Speech Recognition Entitlement Not Appearing in App ID Capabilities
Hello, I recently enrolled in the Apple Developer Program and created an App ID with the bundle ID com.echo.eyes.voice. I am trying to enable Speech Recognition in the App ID capabilities list, but the option does not appear — even after waiting over a week since my membership was activated. I’ve already: Confirmed my Apple Developer account is active Checked the Identifiers section in the Developer portal Tried editing the App ID, but Speech Recognition is not listed Contacted both Developer Support and Developer Technical Support (Case #102594089120), but was told to post here for help My app uses Capacitor + the @capacitor-community/speech-recognition plugin. I need the com.apple.developer.speech-recognition entitlement to appear so I can use native voice input in iOS. I would really appreciate help from an Apple engineer or anyone who has faced this issue. Thank you, — Daniel Colyer

Speech recognition
Hello, I’ve followed all the steps you recommended and confirmed that the entitlement is correctly added in Xcode, but the provisioning profile still fails. I believe the issue is that my App ID com.echo.eyes.app is missing the com.apple.developer.speech-recognition entitlement on Apple’s end. Could you please manually add this entitlement to my App ID, or guide me on how to get it attached? I’ve already added it locally and confirmed the error in Xcode is due to it not being in the provisioning profile. .

SFSpeechRecognizer is not working inside visionOS 2.4 simulator
I know there has been issues with SFSpeechRecognizer in iOS 17+ inside the simulator.

Spotlight search by keywords setuped in NSUserActivity doesn't work
Hey there! I faced issue in iOS 18 and newer when Spotlight search doesn't show my App in results. In older versions it works. Here is my code: func configureUserActivitity(with id: String, keywords: [String]) { let activity = NSUserActivity(activityType: id) activity.contentAttributeSet = self.defaultAttributeSet activity.isEligibleForSearch = true activity.keywords = Set(keywords) activity.becomeCurrent() self.userActivity = activity } I didn't find any reasons why it doesn't work now. Maybe I should report a bug?

save audio file in iOS 18 instead of iOS 12
I'm able to get text to speech to audio file using the following code for iOS 12 iPhone 8 to create a car file: audioFile = try AVAudioFile( forWriting: saveToURL, settings: pcmBuffer.format.settings, commonFormat: .pcmFormatInt16, interleaved: false) where pcmBuffer.format.settings is: [AVAudioFileTypeKey: kAudioFileMP3Type, AVSampleRateKey: 48000, AVEncoderBitRateKey: 128000, AVNumberOfChannelsKey: 2, AVFormatIDKey: kAudioFormatLinearPCM] However, this code does not work when I run the app in iOS 18 on iPhone 13 Pro Max. The audio file is created, but it doesn't sound right. It has a lot of static and it seems the speech is very low pitch. Can anyone give me a hint or an answer?

Live Captions only partially works - help?
Hope it's okay to post here - I haven't gotten resolution anywhere else. Apple's iOs Live Captions is supposed to translate speech into written text either on the phone (works like a charm!) or via microphone (think meeting in a conference room). Microphone doesn't work anywhere, anytime on a new iPhone 14 purchased November 2024. Anyone out there want to fix this and help a lot of people who have trouble hearing? I'm part of an entire generation that didn't know we were supposed to protect our hearing at concerts and clubs and worse, thought it was cool to snag a spot by the speakers...

SFSpeechRecognizer throws User denied access to speech recognition
I have created an app where you can speak using SFSpeechRecognizer and it will recognize you speech into text, translate it and then return it back using speech synthesis. All locales for SFSpeechRecognizer and switching between them work fine when the app is in the foreground but after I turn off my screen(the app is still running I just turned off the screen) and try to create new recognitionTask it it receives this error inside the recognition task: User denied access to speech recognition. The weird thing about this is it only happens with some languages. The error happens with Croatian or Hungarian locale for speech recognition but doesn't with English or Spanish locale.

Unclear interimResults Web Speech API implementation in Safari iOS (WebKit)
Hi all! I have been working on a web speech recognition service using the Web Speech API. This service is intended to work on smartphones, primarily Chrome on Android and Safari (or WebKit WebView) on iOS. In my specific use case, I need to set the properties continuous = true and interimResults = true. However, I have noticed that interimResults = true does not always work as expected in WebKit. I understand that this setting should provide fast, native, on-device speech recognition with isFinal = false. However, at times, the recognition becomes throttled and slow, yielding isFinal = true and switching to cloud-based recognition. To confirm whether the recognition is cloud-based, I tested it by disabling the internet connection before starting speech recognition. In some cases, recognition fails entirely, which suggests that requiresOnDeviceRecognition = false is being applied. (Reference: SFSpeechRecognitionRequest.requiresOnDeviceRecognition) I believe this is not the expected behavior when setting interimResults = true. I have researched the native services used by the Web Speech API on iOS devices, and the following links seem relevant: • SFSpeechRecognizer • SFSpeechRecognitionRequest.shouldReportPartialResults • SFSpeechRecognizer.supportsOnDeviceRecognition • Recognizing speech in live audio • Apple Developer Forums Discussion I found that setRequiresOnDeviceRecognition and setShouldReportPartialResults appear to be set correctly, but apparently, they do not work as expected: WebKit Source Code

Error throws while using the speech recognition service in my app
Recently I updated to Xcode 14.0. I am building an iOS app to convert recorded audio into text. I got an exception while testing the application from the simulator(iOS 16.0). [SpeechFramework] -[SFSpeechRecognitionTask handleSpeechRecognitionDidFailWithError:]_block_invoke Ignoring subsequent recongition error: Error Domain=kAFAssistantErrorDomain Code=1101 "(null)" Error Domain=kAFAssistantErrorDomain Code=1107 "(null)" I have to know what does the error code means and why this error occurred.

How to uninstall/delete Voice Control on macOS?
How to uninstall/delete Voice Control on macOS so that I can test my app for the case when the initial use of Voice Control causes it to be downloaded from Apple? Is there a folder in the macOS System or Library to delete to force a re-download of Voice Control? My macOS app uses the older NSSpeechRecognizer to handle speech commands, but to use NSSpeechRecognizer required authorization via [SFSpeechRecognizer requestAuthorization...]. I do this and on a macOS system it can trigger a download of Voice Control, the macOS feature. An alert appears with: "A 390 MB download is required to use speech recognition features in MyApp. You may need to quit and open MyApp again after download completes."

AVSpeechUtterance Mandarin voice output replaced by SIRI language setting after upgraded the IOS to 18
Hi, Apple's engineer. Hoping that you can reply to this one. We're developing a Text-to-Speak app. Everything went well until the IOS got upgraded to 18. AVSpeechSynthesisVoice(language: "zh-CN") is running well under IOS 16 AND IOS 17. It speaks Mandarin correctly. In IOS 18, we noticed that Siri's Language setting interrupted the performance of AVSpeechSynthesisVoice. It plays Cantonese instead of Mandarin. Buggy language setting in Siri that affects the AVSpeechSynthesisVoice : Chinese (Cantonese - China mainland) Chinese (Cantonese -Hong Kong)

Any way to adjust the speechRecognitionMetadata pause duration?
Speech Framework I've been checking for SFSpeechRecognitionMetadata to determine the end of a sentence when using Voice Recognition. Yet it doesn't detect small pauses but only large ones, so that I've transcribed basically an entire paragraph before going onto the next one. Besides implementing your own timer, are there any other ways to have more natural pauses to detect the end of sentences, similar to the browser's Web Speech recognition? Since it's in Safari, I assume there should be some similar feature that can be equivalent in MacOS.

Speech synthesis from Safari app extension
I'm making a Safari extension for learning languages. I need speech synthesis for any language the user chooses to learn. I initially tried to make this work within JavaScript, but Safari 18 doesn't reliably list voices for all languages on the web SpeechSynthesis API as described here: https://stackoverflow.com/questions/79179072/how-do-you-use-a-japanese-voice-with-speechsynthesis-in-safari-ios-18 As a workaround, I've had to use AVSpeechSynthesizer in SafariWebExtensionHandler (NSExtensionRequestHandling implementation for the extension). This works in the simulator but not on a real device. I've found this note from Apple in a StackOverflow reply: "Safari extensions are very short-lived, hence not fit for audio playback or speech synthesis. Not being able to validate an app extension in Xcode with a manually-added plist entry for background audio is the designed behavior. The general recommendation is to synthesize speech using JavaScript in conjunction with the Web Speech API." Unfortunately, the suggestion to use the Web Speech API is unsuitable as I just explained. Is there a way to set up a background process in the host app that can do speech synthesis? The app extension would need a way to communicate with this process, and start it if it's not running. Is that possible?

How to implement continuous speech recognition in the background?
Hi, I'd like to develop an app which runs speech recognition even after going into background. I know I can accomplish this using audio background mode and the process the audio but I am not sure if this workaround would get accepted into App Store because of the processing limitations while in the background. How can I accomplish this while still being compliant with Apples privacy policy and other restrictions? Thanks, Marek

Speech Recognizer Clears Transcription After Pause on iOS 18.0
Description: I have encountered an issue with SFSpeechRecognizer on iOS 18.0. During live dictation, if a natural pause (e.g., 1-2 seconds) is introduced, the previously transcribed text is cleared, and the transcription starts over. This behavior makes it difficult to use the API for real-time speech recognition scenarios where pauses are expected. Steps to Reproduce: Open Apple's demo app "SpokenWord". Start the dictation process using SFSpeechRecognizer. Speak a few words, pause for 1-2 seconds, and then continue speaking. Observe that the previously transcribed text is truncated, and the transcription starts anew. Expected Behavior: The transcription should continue appending new results to the previous ones after a natural pause, maintaining a seamless user experience. Observed Behavior: After a pause, the transcription resets, clearing previously transcribed text. Impact: This behavior makes the SFSpeechRecognizer API unreliable for scenarios requiring continuous speech recognition with intermittent pauses. Additional Information: iOS Version: 18.0 Device: [Specify your device, e.g., iPhone 13 Pro] Speech Recognizer Locale: [Specify locale, e.g., en-US] App Behavior: Issue persists in both Apple's demo app ('SpokenWord') and custom implementations.

(iOS 18) SFSpeechRecognitionResult providing new text after a gap in speaking
Here is the demo from Apple's site This issues is specific to iOS 18. When running this demo, we are getting new text when we have a gap in speaking, the recognitionTask(with:resultHandler:) provides new text which is only spoken after the gap and not the concatenation of old text and the new spoken text.

save audio file in iOS 18 instead of iOS 12
I'm able to get text to speech to audio file using the following code for iOS 12 iPhone 8 to create a car file: audioFile = try AVAudioFile( forWriting: saveToURL, settings: pcmBuffer.format.settings, commonFormat: .pcmFormatInt16, interleaved: false) where pcmBuffer.format.settings is: [AVAudioFileTypeKey: kAudioFileMP3Type, AVSampleRateKey: 48000, AVEncoderBitRateKey: 128000, AVNumberOfChannelsKey: 2, AVFormatIDKey: kAudioFormatLinearPCM] However, this code does not work when I run the app in iOS 18 on iPhone 13 Pro Max. The audio file is created, but it doesn't sound right. It has a lot of static and it seems the speech is very low pitch. Can anyone give me a hint or an answer?

Live Captions only partially works - help?
Hope it's okay to post here - I haven't gotten resolution anywhere else. Apple's iOs Live Captions is supposed to translate speech into written text either on the phone (works like a charm!) or via microphone (think meeting in a conference room). Microphone doesn't work anywhere, anytime on a new iPhone 14 purchased November 2024. Anyone out there want to fix this and help a lot of people who have trouble hearing? I'm part of an entire generation that didn't know we were supposed to protect our hearing at concerts and clubs and worse, thought it was cool to snag a spot by the speakers...

SFSpeechRecognizer throws User denied access to speech recognition
I have created an app where you can speak using SFSpeechRecognizer and it will recognize you speech into text, translate it and then return it back using speech synthesis. All locales for SFSpeechRecognizer and switching between them work fine when the app is in the foreground but after I turn off my screen(the app is still running I just turned off the screen) and try to create new recognitionTask it it receives this error inside the recognition task: User denied access to speech recognition. The weird thing about this is it only happens with some languages. The error happens with Croatian or Hungarian locale for speech recognition but doesn't with English or Spanish locale.

Unclear interimResults Web Speech API implementation in Safari iOS (WebKit)
Hi all! I have been working on a web speech recognition service using the Web Speech API. This service is intended to work on smartphones, primarily Chrome on Android and Safari (or WebKit WebView) on iOS. In my specific use case, I need to set the properties continuous = true and interimResults = true. However, I have noticed that interimResults = true does not always work as expected in WebKit. I understand that this setting should provide fast, native, on-device speech recognition with isFinal = false. However, at times, the recognition becomes throttled and slow, yielding isFinal = true and switching to cloud-based recognition. To confirm whether the recognition is cloud-based, I tested it by disabling the internet connection before starting speech recognition. In some cases, recognition fails entirely, which suggests that requiresOnDeviceRecognition = false is being applied. (Reference: SFSpeechRecognitionRequest.requiresOnDeviceRecognition) I believe this is not the expected behavior when setting interimResults = true. I have researched the native services used by the Web Speech API on iOS devices, and the following links seem relevant: • SFSpeechRecognizer • SFSpeechRecognitionRequest.shouldReportPartialResults • SFSpeechRecognizer.supportsOnDeviceRecognition • Recognizing speech in live audio • Apple Developer Forums Discussion I found that setRequiresOnDeviceRecognition and setShouldReportPartialResults appear to be set correctly, but apparently, they do not work as expected: WebKit Source Code

Error throws while using the speech recognition service in my app
Recently I updated to Xcode 14.0. I am building an iOS app to convert recorded audio into text. I got an exception while testing the application from the simulator(iOS 16.0). [SpeechFramework] -[SFSpeechRecognitionTask handleSpeechRecognitionDidFailWithError:]_block_invoke Ignoring subsequent recongition error: Error Domain=kAFAssistantErrorDomain Code=1101 "(null)" Error Domain=kAFAssistantErrorDomain Code=1107 "(null)" I have to know what does the error code means and why this error occurred.

How to uninstall/delete Voice Control on macOS?
How to uninstall/delete Voice Control on macOS so that I can test my app for the case when the initial use of Voice Control causes it to be downloaded from Apple? Is there a folder in the macOS System or Library to delete to force a re-download of Voice Control? My macOS app uses the older NSSpeechRecognizer to handle speech commands, but to use NSSpeechRecognizer required authorization via [SFSpeechRecognizer requestAuthorization...]. I do this and on a macOS system it can trigger a download of Voice Control, the macOS feature. An alert appears with: "A 390 MB download is required to use speech recognition features in MyApp. You may need to quit and open MyApp again after download completes."

AVSpeechUtterance Mandarin voice output replaced by SIRI language setting after upgraded the IOS to 18
Hi, Apple's engineer. Hoping that you can reply to this one. We're developing a Text-to-Speak app. Everything went well until the IOS got upgraded to 18. AVSpeechSynthesisVoice(language: "zh-CN") is running well under IOS 16 AND IOS 17. It speaks Mandarin correctly. In IOS 18, we noticed that Siri's Language setting interrupted the performance of AVSpeechSynthesisVoice. It plays Cantonese instead of Mandarin. Buggy language setting in Siri that affects the AVSpeechSynthesisVoice : Chinese (Cantonese - China mainland) Chinese (Cantonese -Hong Kong)

Any way to adjust the speechRecognitionMetadata pause duration?
Speech Framework I've been checking for SFSpeechRecognitionMetadata to determine the end of a sentence when using Voice Recognition. Yet it doesn't detect small pauses but only large ones, so that I've transcribed basically an entire paragraph before going onto the next one. Besides implementing your own timer, are there any other ways to have more natural pauses to detect the end of sentences, similar to the browser's Web Speech recognition? Since it's in Safari, I assume there should be some similar feature that can be equivalent in MacOS.

Speech synthesis from Safari app extension
I'm making a Safari extension for learning languages. I need speech synthesis for any language the user chooses to learn. I initially tried to make this work within JavaScript, but Safari 18 doesn't reliably list voices for all languages on the web SpeechSynthesis API as described here: https://stackoverflow.com/questions/79179072/how-do-you-use-a-japanese-voice-with-speechsynthesis-in-safari-ios-18 As a workaround, I've had to use AVSpeechSynthesizer in SafariWebExtensionHandler (NSExtensionRequestHandling implementation for the extension). This works in the simulator but not on a real device. I've found this note from Apple in a StackOverflow reply: "Safari extensions are very short-lived, hence not fit for audio playback or speech synthesis. Not being able to validate an app extension in Xcode with a manually-added plist entry for background audio is the designed behavior. The general recommendation is to synthesize speech using JavaScript in conjunction with the Web Speech API." Unfortunately, the suggestion to use the Web Speech API is unsuitable as I just explained. Is there a way to set up a background process in the host app that can do speech synthesis? The app extension would need a way to communicate with this process, and start it if it's not running. Is that possible?

How to implement continuous speech recognition in the background?
Hi, I'd like to develop an app which runs speech recognition even after going into background. I know I can accomplish this using audio background mode and the process the audio but I am not sure if this workaround would get accepted into App Store because of the processing limitations while in the background. How can I accomplish this while still being compliant with Apples privacy policy and other restrictions? Thanks, Marek

Speech Recognizer Clears Transcription After Pause on iOS 18.0
Description: I have encountered an issue with SFSpeechRecognizer on iOS 18.0. During live dictation, if a natural pause (e.g., 1-2 seconds) is introduced, the previously transcribed text is cleared, and the transcription starts over. This behavior makes it difficult to use the API for real-time speech recognition scenarios where pauses are expected. Steps to Reproduce: Open Apple's demo app "SpokenWord". Start the dictation process using SFSpeechRecognizer. Speak a few words, pause for 1-2 seconds, and then continue speaking. Observe that the previously transcribed text is truncated, and the transcription starts anew. Expected Behavior: The transcription should continue appending new results to the previous ones after a natural pause, maintaining a seamless user experience. Observed Behavior: After a pause, the transcription resets, clearing previously transcribed text. Impact: This behavior makes the SFSpeechRecognizer API unreliable for scenarios requiring continuous speech recognition with intermittent pauses. Additional Information: iOS Version: 18.0 Device: [Specify your device, e.g., iPhone 13 Pro] Speech Recognizer Locale: [Specify locale, e.g., en-US] App Behavior: Issue persists in both Apple's demo app ('SpokenWord') and custom implementations.
