We shrank our steerable small TTS to 11.84 MB. WER is unchanged, UTMOS drops ~0.1 [p]

A while back I posted SteerTTS v1, a small English TTS you steer with numbers (https://huggingface.co/WhissleAI/steer-tts). Today I am releasing the edge variant: https://huggingface.co/WhissleAI/steer-tts-edge Size: everything an app has to ship (weights, voices, text front end and Python runtime) totals 11.84 MB. How: Acoustic model (9.25M params, attention + bidirectional Mamba-3) is quantization-aware trained to int4 6.2M-param Vocos-style vocoder is distilled from charactr/vocos-mel-24khz, also int4 QAT Text front end is pure numpy, with no NLTK, g2p_en, torchaudio or num2words at runtime
