Here phrase is not declared, can you use params.phrase.c_str()?

Yes that was a typo from me, because I did a few changes at the same time. It is indeed params.phrase.c_str(). Already have changed the rng from the other pull request, you could also uncomment the rng.seed(params.seed);.

//auto result = vits_model_process(model, params.phrase.c_str(), params.n_threads);
if (result.size > 0) {
printf("Generated: %d samples of audio %f %f %f\n", result.size, result.data[0], result.data[1],
result.data[2]);
printf("Wrote to file: %s\n", write_wav("output.wav", result.data, result.size) ? "true" : "false");
printf("Wrote to file: %s\n", write_wav(params.output_path, result.data, result.size) ? "true" : "false");
}
vits_free_result(result);
vits_free_model(model);
