About Inside/VC - Voice AI Market Map - July 2025
This Voice AI Market Map, curated by Inside/VC and sourced from Lightspeed, provides a snapshot of the voice AI ecosystem as of September 2024. It categorizes key players into three layers: Application (e.g., Slang AI, PolyAI, Colleen AI), Middleware (e.g., Sindarin, Vapi, Hume AI, Retell AI), and Model (e.g., AssemblyAI, Deepgram, ElevenLabs, OpenAI). The map highlights notable movement in applied use cases (call centers, healthcare, real estate), increasing competition in middleware, and a shift in STT/TTS players from feature providers to infrastructure companies. Hyperscalers are circling, but the window for breakout startups remains open.
