AI voice startups raised $7B in Q1 '26, up from $1B in Q1 '25, as OpenAI and Google position voice as the primary interface for a new generation of AI agents.

Engineers building AI products will face growing pressure to adopt voice-first architectures and real-time audio processing capabilities as table stakes rather than differentiators.
