Detailed Description

This struct supports both simple multi-speaker synthesis and more advanced zero-shot or reference-conditioned models.

Example for Pocket TTS:

SherpaOnnxGenerationConfig cfg;
memset(&cfg, 0, sizeof(cfg));
cfg.speed = 1.0f;
cfg.reference_audio = wave->samples;
cfg.reference_audio_len = wave->num_samples;
cfg.reference_sample_rate = wave->sample_rate;
cfg.extra = "{\"max_reference_audio_len\": 10.0, \"seed\": 42}";
