SpeechAnalyzer speech to text wwdc sample app

I have tried building with the Xcode beta 1 and beta 2 and both get the above error.

I encountered the same thing with my beta 2 / iPhone 15 Pro environment, and have also tried deallocating, allocating, triggering uninstalls, forcing download/install etc in various combinations with my en-US locale, not able to get anything other than the error message described above. This same code was working yesterday on beta 1.

Same here, this got broken with iOS 24 beta 2. Let's hope it gets fixed with beta 3 onwards

Same error here with beta 2

Same. Code that was working in Beta 1 now produces this error in Beta 2.

Hopefully someone from Apple is watching this. I know, I know, "File a feedback!", but after years of them being ignored, it's not worth the time that could better be spent elsewhere.

Same for me.

I submitted a feedback on this. It is: https://feedbackassistant.apple.com/feedback/18500374

I have the same issue and it was perfect on Beta 1, now with Beta 2 it's broken. I am so sad, I had features that relied 100% on code that would use this sample example. UserInfo={NSLocalizedDescription=Cannot use modules with unallocated locales [en_US (fixed en_US)]}

Please FIX THIS NOW IN BETA 3!!

I'm also having this issue and quite disappointed that no Apple engineers have replied to / updated this thread given it's been a week and people are testing out this new API.

It looks like from my logs it could be some very simple bug with a comparison involving - vs _ as my allocated locales are [en_GB (fixed en_GB)] and my error is Cannot use modules with unallocated locales [en-GB (fixed en-GB)].

So perhaps it's seeing the en_GB and en-GB as incompatible?

Also experiencing this on macOS 26 beta 2, Xcode 26.0 beta 2:

SpeechAnalyzer: Input loop ending with error: Error Domain=SFSpeechErrorDomain Code=10 "Cannot use modules with unallocated locales [en_GB (fixed en_GB)]"

It happens with both en-GB and en-US.

Strangely, no such error is thrown with ja-JP. My first recording with that locale didn't get transcribed, but my second one did.

This is fixed in beta 3.

I'm still having the issue in the beta 3:

SpeechAnalyzer: Input loop ending with error: Error Domain=SFSpeechErrorDomain Code=10 "Cannot use modules with unallocated locales [en_US (fixed en_US)]" UserInfo={NSLocalizedDescription=Cannot use modules with unallocated locales [en_US (fixed en_US)]}

I am fixed it using the code

public func ensureModel(transcriber: SpeechTranscriber, locale: Locale) async throws {
        guard await supported(locale: locale) else {
            throw TranscriptionError.internalFailure("localeNotSupported")
        }
        try await downloadIfNeeded(for: transcriber)
//        if await installed(locale: locale) {
//            return
//        } else {
//            try await downloadIfNeeded(for: transcriber)
//        }
    }

    func downloadIfNeeded(for module: SpeechTranscriber) async throws {
        if let downloader = try await AssetInventory.assetInstallationRequest(supporting: [module]) {
            Log.transcription.info("SpeechTranscriber download \(downloader.progress)")
//            self.downloadProgress = downloader.progress
            try await downloader.downloadAndInstall()
        }
    }

Hi,

I'm encountering an issue across recent Xcode 26 betas while working with speech recognition.

In Xcode 26 Beta 1 & 2, I received the following errors:

localeNotSupported could not record: invalidAudioDataType

In Xcode 26 Beta 3, the issue has changed. I'm now getting this error:

SpeechTranscriber cannot be initialized with an unsupported locale: en_US (fixed en_US). Please consult SpeechTranscriber.supportedLocales. SpeechAnalyzer: Input loop ending with error: Error Domain=SFSpeechErrorDomain Code=4 "SpeechTranscriber initialized with unsupported locale" UserInfo={NSLocalizedDescription=SpeechTranscriber initialized with unsupported locale} speech recognition failed.

I am using "en_US" as the locale, which has always worked in previous versions. I’ve confirmed that the microphone permission is granted, and I’ve tested on a real device running iOS 26 Beta.

Is there any new requirement or setting that needs to be enabled in Xcode 26 Beta or iOS 26 beta to allow the SpeechTranscriber to work with this locale? Do I need to configure anything in the device settings?

Any help or guidance would be greatly appreciated.

Thanks!

I'm encountering a similar issue. When I try to run SpeechTranscriber I'm running into this error despite both en_GB and en_US being listed in the SupportedLocales. Tried on Beta 1 and Beta 3 on xcode and ipad.
