config.model.pocket.lm_main =
    "./sherpa-onnx-pocket-tts-int8-2026-01-26/lm_main.int8.onnx";
config.model.pocket.encoder =
    "./sherpa-onnx-pocket-tts-int8-2026-01-26/encoder.onnx";
config.model.pocket.decoder =
    "./sherpa-onnx-pocket-tts-int8-2026-01-26/decoder.int8.onnx";
config.model.pocket.text_conditioner =
    "./sherpa-onnx-pocket-tts-int8-2026-01-26/text_conditioner.onnx";
