# October 9, 2026 Murf added word-level timestamps to its [WebSocket streaming API]() for Falcon 2. Set add\_word\_timestamps to true at the top level of the frame, next to text. Murf says to keep it out of voice\_config, where it's ignored without an error. Once it's on, it applies to the whole connection. Falcon then sends each spoken word with start\_s and end\_s in seconds. These arrive as separate JSON frames mixed in with the audio frames, not inside the base64 audio field. This helps most with [Murf AI]() voice agents that handle barge-in. When a user interrupts, stop playback and send a clear frame with that turn's context\_id. Then drop any audio and timestamps past the current playback position. The timestamps you keep are the words the user actually heard. The word field is normalized spoken text, so "$50" comes back as "fifty dollars" and "2pm" as "two p m". Word timestamps work in every locale except Chinese, Japanese, and Korean.
