[Bug]: iOS dictation transcribes Italian speech as Spanish on 2.3.0 #34585

Area

apps/mobile — iOS built-in composer dictation

Summary

When I speak Italian using T3 Code's built-in dictation on iOS, the transcription comes out as Spanish, as though the wrong recognition language were being used.

I updated the iOS app to 2.3.0, the latest version available to me, and the problem persists.

Steps to reproduce

1. On an iPhone 18 Pro running iOS 27.2.1, with preferred languages ordered English first, Italian second (no Spanish), open a thread in T3 Code 2.3.0.
2. With the voice transcription destination set to This device, start dictation using the app's built-in microphone.
3. Speak Italian.
4. Finish dictation and inspect the transcribed text.

This describes my observed workflow; it has not been independently reproduced on another device.

Expected behavior

Italian speech should be transcribed accurately in Italian. A way to explicitly select Italian would also help if automatic language selection cannot reliably handle this case.

Actual behavior

Italian speech is interpreted/transcribed as Spanish, making the integrated dictation unsuitable for my Italian prompts. Updating to 2.3.0 did not resolve it. The reporter says this happens every time, not intermittently. It has never worked correctly for Italian, including when dictating long sentences; the failure is not limited to short phrases that might be ambiguous.

Impact

Major degradation of Italian voice input.

I currently have to fall back to iOS keyboard dictation, which I find poor, or use a third-party service. On a Mac I have more flexibility to install alternative tools or use services through something like Raycast; on iOS this is more cumbersome. Having reliable dictation inside T3 Code would make a substantial difference.

Version or commit

iOS app: 2.3.0.
Exact build number / OTA revision not recorded.

Environment

• Device: iPhone 18 Pro.
• iOS: 27.2.1, reported as the latest available release; exact OS build not recorded.
• Preferred languages, in order: English, Italian. Spanish is not in the list.
• Voice transcription destination: This device (on-device transcription).
• App-specific language override not yet recorded.
• Spoken language: Italian.
• Observed output language: Spanish.

Related work / investigation

• [Bug]: iPhone 1.2.0 voice input recognizes Korean speech as unrelated English words #12743 reported a related wrong-language transcription problem for Korean.
• fix(mobile): use preferred languages for on-device iPhone dictation #31800 addresses preferred-language selection for on-device iPhone dictation.
• Discussion #21742 requests an explicit dictation-language selector.

I have not verified whether the changes in #31800 are included in my installed 2.3.0 build, or whether this has the same root cause. This report records the Italian-to-Spanish behavior that remains on my device.

Are there known iOS/transcription-engine limitations affecting Italian, or settings/diagnostics that would help identify the language actually selected?
