The **acoustic model is unchanged** (that's where the zh-en quality lives); only the vocoder is replaced — the stock 16 kHz `vocos-16khz-univ.onnx` is distilled into an **8 kHz** `vocos-8khz-univ.onnx`. Built for a phone-attendant product on **Jetson Nano gen1 CPU** (ONNX Runtime CPU via sherpa-onnx): the audio leaves through an 8 kHz G.711 channel, so native 8 kHz output avoids the on-device 16k→8k resample and ships a smaller vocoder. Drop-in for the stock `sherpa-onnx-offline-tts` — only the model dir changes. ## Listen — zh/en code-mixed (rendered by stock sherpa-onnx, 8 kHz) | text | 8 kHz | through G.711 | |------|-------|---------------| | 您好,這裡是台灣精密,請問您要找 David 還是 Michael? | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_1_8k.wav"></audio> | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_1_8k_g711.wav"></audio> | | Kevin 說下午的 meeting 改到 Zoom 線上進行。 | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_2_8k.wav"></audio> | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_2_8k_g711.wav"></audio> | | Please hold,我幫您查詢 VIP 會員資料,請稍候。 | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_3_8k.wav"></audio> | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_3_8k_g711.wav"></audio> | | The quick brown fox 和敏捷的棕色狐狸,一起測試中英文。 | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_4_8k.wav"></audio> | <audio controls src="https://huggingface.co/Luigi/matcha-zh-en-8k/resolve/main/samples/sample_4_8k_g711.wav"></audio> | Full A/B vs the 16 kHz original and vs MeloTTS-8k: [Luigi/zh-en-tts-8k-comparison](https://huggingface.co/datasets/Luigi/zh-en-tts-8k...
