TTSKit v0.4
WhisperKit is expanding into text-to-speech!
TTSKit adds a new library for on-device text-to-speech using Core ML-accelerated Qwen3-TTS models (CustomVoice 0.6B and 1.7B in this first release) with real-time streaming playback on Apple Silicon. In this first PR, we're introducing the library into the WhisperKit package (WhisperKit will be renamed to reflect the new multi-Kit nature of Argmax Open-source SDK) as an optional import to add real-time TTS capabilities with a state-of-the-art open-source model, either on its own or as a complement to WhisperKit speech-to-text.
On-device speech recognition
Optimized for Apple Silicon devices
Supports multiple Whisper models
