A Indic Parler-TTS model by AI4Bharat, from ai4bharat/indic-parler-tts, packaged for phoonnx, our ONNX text-to-speech library.

Model details

Architecture	Indic Parler-TTS
Upstream	ai4bharat/indic-parler-tts

Text input	Unicode codepoints of the text

How to use

pip install --pre phoonnx

import wave
from phoonnx.model_manager import TTSModelManager

manager = TTSModelManager()
manager.load()
manager.merge_default_voices()

voice = manager.voices["indic_parler/aditi/bn"].load()

with wave.open("output.wav", "wb") as wav_file:
    text = "..."  # a sentence in bn
    voice.synthesize_wav(text, wav_file)

In OVOS, phoonnx installs the ovos-tts-plugin-phoonnx plugin. Select the voice in mycroft.conf:

{"tts": {"module": "ovos-tts-plugin-phoonnx", "ovos-tts-plugin-phoonnx": {"voice": "indic_parler/aditi/bn"}}}

Text front end

phoonnx hands the text to scriptconv, our text conversion library, which normalises it and turns it into the model's input:

• unicode: UnicodeCodepointPhonemizer from scriptconv.phonemizers.base, in scriptconv itself.
