murf/gen2

Murf Speech Gen 2, the studio-voiceover model Murf launched in July 2024, with 44.1 kHz output and speaking styles such as documentary and audiobook. Murf retired it from streaming in October 2026; it remains on the non-streaming Synthesize Speech endpoint.

Provider Notes

Falcon 2 is Murf's $0.01/1K-character low-latency model and supports streaming HTTP plus multiplexed WebSockets. Gen2 is $0.03/1K characters and adds the Synthesize Speech endpoint, word durations, requested audio duration, variation, and zero-retention Base64 output; Murf decommissioned Gen2 streaming on 2026-10-05, so Gen2 is served through Synthesize Speech only. Both models support MP3, FLAC, WAV, Ogg, PCM, μ-law, A-law, regional hosts, voice styles, rate, pitch and locale; only Falcon 2 works on AudioLab's speech WebSocket. Murf's US-East WebSocket currently falls back to Gen2 even when Falcon 2 is selected, so AudioLab pins implicit/global Falcon 2 WebSocket sessions to Murf's US-West host; an explicitly selected residency region remains unchanged. Murf's native WebSocket voice field is camelCase voiceId; AudioLab also accepts voice_id as an input alias and serializes the native form upstream. Provider errors terminate the stream and release every credit reserve. Requests are capped at 3,000 characters per HTTP request or WebSocket context; use the live Murf voice catalog because model voice/style/locale availability differs.
