feat(tts): on-device neural voice — WAV/MP3 download + pauses - #273
Merged
Conversation
Browser (OS) voices can't be recorded, so this adds an on-device neural TTS (MMS-TTS via @huggingface/transformers, loaded through the same /hf proxy as Whisper) that generates real audio samples. Users can play the result, download WAV or MP3 (lamejs), and insert pauses with [pause] markers or blank lines (silence spliced into the buffer). OS-voice playback is unchanged. Pure tts-audio.lib.ts (WAV encode, PCM, silence, pause-split) unit-tested. New dep: @breezystack/lamejs.

Adds downloadable audio and pauses to Text-to-Speech, requested by a user.
Why: the browser/OS voices (Web Speech) genuinely can't be captured to a file. So this adds an on-device neural voice (MMS-TTS via
@huggingface/transformers, loaded through the same/hfproxy as Whisper) that produces real audio samples.New in the tool (OS-voice playback unchanged):
@breezystack/lamejs).[pause](or leave a blank line) and set a pause length — silence is spliced into the audio buffer.Pure
tts-audio.lib.ts(WAV encode, PCM16, silence concat, pause-split) unit-tested (7 tests). transformers + lamejs are lazy-loaded chunks (no impact on the initial page). EN + ID FAQ updated.Verify: 1365 tests green, lint 0 errors, build OK.
