OptiSpeech ConvNext-TTS es-CO-Marcia v0

OptiSpeech ConvNext-TTS es-CO-Marcia v0 is a Spanish single-speaker text-to-speech ONNX export trained with the OptiSpeech framework. The speaker is Marcia, targeting Colombian Spanish (es-CO).

This model uses the OptiSpeech Spanish TextProcessor at inference time. No separate gruut_*_symbols.py file is needed for this export.

Training Source

This export was staged from:

text

logs/train/es_speaker_ddp/convnext-tts-ES-Marcia.onnx
logs/train/es_speaker_ddp/runs/2026-06-22_18-42-17/

ONNX Inference

Run inference from an OptiSpeech checkout with the Spanish text processor dependencies installed:

source .venv/bin/activate
uv sync --extra es

python onnx_inference_es.py \
  --model_path convnext-tts-es-CO-Marcia-v0.onnx \
  --input "Hola, esta es una prueba de síntesis de voz en español colombiano." \
  --output_path outputs \
  --output_name marcia_v0.wav

The ONNX model expects:

x: phoneme/token IDs from optispeech.text.TextProcessor(languages=["es"])
x_lengths: input sequence lengths
scales: duration, pitch, and energy factors

The helper script handles text normalization, Spanish phonemization/tokenization, ONNXRuntime execution, and WAV writing.
