| Description | Sparrow-2 is a real-time AI model built specifically for natural conversational turn-taking -- handling the timing, interruptions, and back-and-forth rhythm of real speech -- aimed at developers building voice AI products that need to feel like a natural conversation rather than a stilted question-and-answer exchange. It is aimed at developers building voice agents or voice-first products who need the underlying turn-taking to feel human, not just accurate speech recognition. | Perplexity AI is a conversational answer engine that searches the web in real-time and provides cited, accurate answers. Used by 10+ million users who need research-grade answers without the noise of a traditional search engine. |
