(Simple AI) Introducing Sentiment: How Tango Hears What Customers Feel

Simple AI introduces Sentiment in Tango, its conversational awareness model, which it says makes Simple the first voice agent on the market to process sentiment directly from audio, scoring confusion, frustration, and happiness from 0 to 3 every 80ms. Tango produces these scores in the same pass over the same audio it already uses for end-of-turn and interruption detection, with no second pipeline or added latency, and works on compressed 8kHz telephony audio. The company describes uses during calls (clarifying, changing course, matching tone) and after calls (reviewing where conversations turned and spotting patterns across many calls).
