LTM Audio: language selection or auto-detect for transcription (non-English speech)

[geertvanzoest]

Summary

LTM Audio currently transcribes all captured speech as if it were English. For users who speak another language (in my case Dutch), the resulting transcripts are unusable: the model force-fits non-English speech into English words, producing garbled text. Downstream, most of these audio events end up classified as "Unclassified Event — content could not be meaningfully analyzed", so the spoken content contributes little to workstream summaries beyond the fact that a conversation took place.

Request

Add language support to the LTM Audio transcription pipeline, ideally one (or both) of:

1. Automatic language detection — detect the spoken language per audio segment and transcribe in that language. This also covers mixed-language workdays (e.g. Dutch meetings and English meetings on the same day), which are common for non-English-native professionals.
2. A manual language setting — a language picker in the LTM Audio settings for users who want deterministic behavior.

Context

• The rest of the LTM Audio chain works well: capture (mic + system audio), speaker diarization, and enrichment into workstream summaries all function as expected. Transcription language is the single remaining gap.
• Widely used open speech models support ~99 languages including strong Dutch performance, so this appears to be a configuration/pipeline limitation rather than a model-capability one.
• I understand LTM Audio is a Preview feature — filing this as early feedback for exactly that reason.

Environment

• PiecesOS 1.0.30 on macOS
• LTM Audio enabled with both microphone input and system audio capture

Happy to provide more detail or test builds.
