Google AI Edge Gallery adds on-device speech recognition and text-to-speech
Google introduced on-device Automatic Speech Recognition and Text-to-Speech in Google AI Edge Gallery, letting apps run multilingual ASR and expressive TTS fully offline alongside on-device SLMs like Gemini Nano and Gemma 4. On Android, ML Kit's new speech models transcribe 100+ languages at 10x real-time speed with an 8.0% to 9.0% Word Error Rate on FLEURS, while the few-step diffusion TTS starts speaking in about 100 ms and generates 24 kHz audio at up to 50x real-time speed. Cross-platform support comes through MediaPipe Tasks and LiteRT with open-weight bundles including Parakeet-TDT 0.6B, PocketTTS 100M, Kokoro-82M and Phonon 31M, demonstrated in the XR Language Teacher showcase and voice-enabled AI Chat.
Why it matters: Google adds fully offline ASR and TTS to AI Edge Gallery, with ML Kit reporting 100+ language transcription at 10x real time and a diffusion TTS that starts speaking in about 100 ms.
