What is a
squawk box?
A squawk box delivers market-moving news and order-flow commentary to traders in real time via audio — no reading required. It lets a trader hear critical headlines while keeping eyes on charts and positions. Here is the history, the technology, and how SquawkNews builds on the concept.
A brief history of the squawk box
How a modern squawk works
The SquawkNews audio layer sits directly on top of the text wire. When a headline is published to the feed, the system evaluates its priority. FLASH and URGENT items are immediately routed to text-to-speech synthesis via the Cartesia TTS engine, which generates an MP3 audio file in under one second. The audio is served to connected browser clients, where it plays through the user's speakers or headphones.
The entire process — from wire publication to audio reaching the listener — takes under three seconds for a FLASH item. ROUTINE items are queued and read in order; ADVISORY items are text-only by default.
This architecture means the squawk scales to unlimited concurrent listeners without a human reader creating a bottleneck. It also means the voice is consistent in tone, pronunciation and speed regardless of market conditions — the audio quality does not degrade during a volatile session when the most headlines are flowing.
Why audio beats reading at news time
A trader watching a chart, managing an open position, or monitoring an order book cannot simultaneously read a scrolling news feed. Audio removes that conflict. A FLASH headline about an FDA decision or an FOMC surprise reaches the trader's ear without requiring them to shift attention. The trader can glance at the terminal to read the full item while the audio continues with the next headline.
This is the same advantage the original trading-floor squawk offered: the desk trader heard news before they saw the price move, because the intercom reached their ear before they looked at the ticker tape.
News → price evidence: audio timing
Below, one case study shows the timestamp of the SquawkNews audio squawk call versus the price move. Audio timing is measured from wire publication, not from when a human might have spoken the headline.

The word "squawk" in the financial context predates the CNBC programme by decades and refers specifically to the audio intercom systems used on trading floors since the 1920s, as described in the history section above.
Frequently asked questions
What does "squawk" mean in trading?
A squawk box is an audio broadcast system that delivers market-moving news, order flow commentary, and price calls to traders in real time. The name comes from the squawk intercom boxes used on trading floors to relay information from wire rooms to the pit. A squawk allows a trader to hear critical information without looking away from charts or an order entry screen.
Is SquawkNews related to CNBC Squawk Box?
No. SquawkNews is an independent financial news service and is not affiliated with, endorsed by, or connected to CNBC or the Squawk Box programme. CNBC Squawk Box is a television programme; SquawkNews is a browser-based real-time news wire with an audio squawk layer. If you reached this page looking for CNBC content, please visit cnbc.com.
What is the difference between a human squawk and TTS squawk?
A human-reader squawk employs a person who reads wire headlines aloud in real time — some paid services charge $200–$400/month for this. A TTS (text-to-speech) squawk uses AI voice synthesis to read headlines the moment they publish. SquawkNews uses AI voice synthesis via Cartesia TTS, which means zero delay between publication and audio — a human reader would need several seconds to begin speaking.
How do I turn on the audio squawk?
Open the LiveCast (/news) or Terminal (/terminal). An audio controls panel appears in the navigation. Enable audio from there. Browsers require a user gesture (a click) before playing audio, so the first headline is spoken after you interact with the controls.
Can I use the squawk without having audio on?
Yes. The text wire and the audio squawk are separate layers on the same underlying feed. The text wire is always active; audio is opt-in. High-priority headlines are visually flagged with FLASH or URGENT tags regardless of whether audio is enabled.
