speakturbo Talk to your Claude! Give your agent the ability to speak to you real time. Ultra fast text to speech with ~90ms latency and 8 built in voices. Quick Start Output explained: ⚡ = first audio received, ▶ = playback started, ✓ = done First Run The first execution takes 2 5 seconds while the daemon starts and loads the model into memory. Subsequent calls are ~90ms to first sound. Usage Available Voices Voice Type alba Female (default) marius Male javert Male jean Male fantine Female cosette Female eponine Female azelma Female Performance Metric Value Time to first sound ~90ms (daemon warm) First run 2 5s (daemon startup) Real time factor ~4x faster Sample rate 24kHz mono Architecture Text Input Encoding: UTF 8 Quotes in text: Use escaping: speakturbo "She said \"hello\"" Long text: Supported, streams as it generates Output Path Security The o flag only writes to directories that are on the allowlist. By default, these are: /tmp and system temp directories Your current working directory ~/.speakturbo/ If you need to write elsewhere, use allow dir : To permanently allow a directory, add it to ~/.speakturbo/config : The config file is one directory per line. Lines starting with are comments. Exit Codes Code Meaning 0 Success (audio played/saved) 1 Error (daemon connection failed, invalid args) When to Use Use speakturbo when: You need instant audio feedback (~90ms) Speed matters more than voice variety Built in voices are sufficient Use speak instead when: You need custom voice cloning (Morgan Freeman, etc.) → speak "text" voice ~/.chatter/voices/morgan freeman.wav You need emotion tags like [laugh] , [sigh] Quality/variety matters more than speed See the speak skill documentation for full usage. Troubleshooting No audio plays: Daemon won't start: First run is slow: This is expected. The daemon needs to load the ~100MB model into memory. Subsequent calls will be fast (~90ms). Daemon Management The daemon auto starts on first use and auto shuts down after 1 hour idle .
