Soniox is the clear choice if you need a production-ready, multilingual speech API with low latency, translation, and enterprise compliance. Wispr is a solid free option for personal dictation on macOS, but its on-device only approach and lack of translation or multi-speaker features make it unsuitable for building voice applications at scale.
