The agent behaved as expected. The voice was clean and clear qnd she pivoted when the calendar API did not pull up the calendar as expected. Great system. Thanks Retell.

Retell setup and deployment is well documented and is available for all to see, even AI products that can do a great job in setting things up and troubleshooting.

Ho utilizzato Retell AI per costruire agenti vocali e l’esperienza è stata positiva. L’editor visuale/no-code rende rapido il prototipaggio, mentre le API permettono integrazioni avanzate per i casi più tecnici. La qualità del TTS è molto valida e la piattaforma offre meccanismi di fallback per mantenere la voce anche in caso di problemi con un provider. Retell dichiara e ottimizza la latenza per conversazioni real-time — nella pratica la fluidità è ottima nella maggior parte dei casi, anche se la latenza finale dipende dal provider TTS/LLM e dal canale telefonico usato. Consigliato se vuoi prototipare e portare in produzione voice agents con controllo tecnico e robustezza enterprise.

I love how you can structure the whole call. Sadly testing your voice agent does cost now. Nevertheless its a great tool to use.
