draft

seyeong-han and others added 3 commits April 16, 2026 10:42
Add the in-progress Voxtral TTS export, runner, parity, and acceptance tooling so the work can be resumed on another machine without losing the current investigation state.

Made-with: Cursor
…NNPACK

Three bugs fixed: codec reshape order (P*T to T*P), flow-matching RNG
(mt19937 to xorshift64+BoxMuller matching C ref), ALiBi slopes off-by-one.
Adds --speaker for live PCM output, parakeet STT gate, quantization
docs and benchmarks.

Authored with Claude.
