AI Simultaneous Interpretation Explained

Simultaneous interpretation has traditionally been a highly specialized, resource-intensive service. It required soundproof booths, complex audio routing, and highly trained human professionals working in pairs. Enter AI Simultaneous Interpretation Systems (SIS).

How AI SIS Works

An AI SIS pipeline typically involves three rapid, highly optimized steps:

1. Speech-to-Text (STT): The speaker's audio is captured and instantly transcribed into text using advanced automatic speech recognition models.
2. Machine Translation (MT): The transcribed text is translated into the target language using neural machine translation, keeping context in mind.
3. Text-to-Speech (TTS): The translated text is synthesized back into natural-sounding audio in the target language.

The Latency Challenge

One of the hardest parts of simultaneous interpretation is controlling delay. If translated audio falls too far behind the speaker, the listener can lose context. Actual delay varies with source speech, language pair, processing, network conditions, and the audio delivery path, so organizers should test the complete event workflow rather than rely on an absolute latency claim.

Accessibility for All

Browser delivery can let attendees listen on their own compatible phones and headphones, which may reduce the need for proprietary receiver rentals when the venue network has been tested for the expected audience load. Venues that already own transmitters and receivers can instead route selected Pikka language channels into that system, keeping audience listening independent of event Wi-Fi.
