PolyAI Releases Dialog-RSN-1: An Audio-Native Dialog Model That Fuses Turn-Taking, Speech Recognition, Function Calling, And Response

PolyAI has introduced Dialog-RSN-1, a dialog model that perceives the caller’s audio directly instead of reading a transcript. It fuses turn-taking, speech recognition, function calling and response generation into one audio-native model, and is already handling live production calls. Key Takeaways Dialog-RSN-1 is audio-aware on the input side only; TTS stays separate, so the output

Drones offer alternative to balloons for weather research

Pre-programmed flights gather data at different altitudes then return to bases to recharge and downloadWeather happens in the boundary layer, the atmosphere from ground level to a few thousand metres, but this can be difficult to study in detail: weather stations are too low, and aircraft are expensive. Instrumented weather balloons are the traditional solution,

Tiny reef fish thrived near seabird islands; where rats wiped birds out, marine food chains changed

Tropical islands are facing a surprising ecological shift as invasive rats disrupt the balance of coral reef ecosystems. By decimating seabird numbers, these rats cut down on essential nutrient contributions to the reefs. As a result, tiny cryptobenthic fish flourish in nutrient-rich spots, while invertebrates find success in less fertile regions, reshaping the food web
