Translation Latency
The time delay between when words are spoken and when the translation appears or is heard by the audience.
Understanding Translation Latency
Translation latency is the total delay from when a speaker says something to when the translated version reaches the listener. In live translation, latency includes the time for speech recognition, language translation, and optionally text-to-speech synthesis. Lower latency means a more natural, real-time experience for the audience. Professional simultaneous interpreters typically have a latency of 2-5 seconds. AI-powered systems can achieve latency as low as 200-500 milliseconds, providing an even more seamless experience.
How Selah Translate Uses Translation Latency
Selah Translate achieves sub-500ms translation latency by using optimized speech recognition (Soniox), fast neural translation, and streaming audio delivery (Opus codec). This near-instantaneous translation creates a seamless experience where the audience reads or hears the translation almost as the speaker is talking.
