Cascaded pipeline
A cascaded pipeline uses separate components for speech-to-text, language generation, and text-to-speech. It gives you direct control over the transcription model, LLM, and voice.Realtime pipeline
A realtime pipeline uses a realtime model for the conversation. Some configurations use realtime audio directly, while others pair a realtime model with a selected text-to-speech voice.Choose a configuration
Select the conversation language first, then choose compatible models and a voice. Review the model’s supported language, context window, and specialization in the builder. Use a representative simulated call to compare:- Transcription accuracy for names, numbers, and domain terms
- Voice quality and pronunciation
- Response latency
- Interruption and endpointing behavior
- Action execution and structured output
