Tiered speech synthesis with over 1,000 voices, 16 languages, 20 Chinese dialects, natural-language delivery direction, and inline emotion tags.
Alibaba CloudGeneración de audioLanzado 20 jul 2026SingaporeEndpoint propietarioNuevoTiered speech synthesis with over 1,000 voices, 16 languages, 20 Chinese dialects, natural-language delivery direction, and inline emotion tags.
Voice selection is tier aware: base voice ids work on both tiers and are automatically matched to the selected model_tier, while the six system voices are locked to one tier. Pitch also shifts the pace of the rendered audio, so pair it with speed when you want to preserve the original duration.
