Custom Voices
You can create a custom Supertonic voice with Supertonic Voice Builder:
Voice Builder lets you record or upload source audio and create a downloadable voice-style JSON for Supertonic. To use a purchased/exported voice in this Unity demo, place the JSON file under Assets/StreamingAssets/Supertonic/VoiceStyles/. The runtime Voice Style Resource Name dropdown is populated from those JSON files by filename, so a file such as MyVoice.json appears as MyVoice.
Inference Pipeline
The Unity runner follows the official Supertonic inference contract through FP16 .sentis model files in StreamingAssets:
duration_predictor_fp16.sentistext_encoder_fp16.sentisvector_estimator_fp16.sentisvocoder_fp16.sentis
The generated waveform is converted into a Unity AudioClip and played through the AudioSource on the demo GameObject.
