Speech to Text for Live Streaming
Speech to text (STT) technology converts spoken language into written text. For streamers, STT means real-time captions that appear on your stream as you speak. This makes your content accessible and opens it up to international audiences.
The challenge for streaming is latency — STT must process audio and produce text within 1-2 seconds to feel "real-time." Not all STT services can handle this. StreamTranslate uses advanced AI, one of the fastest and most accurate STT providers.
