Voice / Speech (2026)

Voice and speech tools turn audio into text and text into natural-sounding speech, and increasingly connect both ends to agents for real-time conversation. The category includes speech recognition toolkits, generative text-to-speech models, voice orchestration platforms and back ends for voice-controlled devices.

For speech recognition, compare supported languages, accuracy on your audio, real-time performance and features such as speaker diarisation. For text-to-speech, listen to samples in your target language and check the license, especially for commercial use. For voice agents, latency is the deciding factor: measure the full round trip from speech to response on your own setup.
