What OpenSpeaker Voice Changer is
OpenSpeaker Voice Changer converts recorded speech into another voice through ElevenLabs speech-to-speech while keeping the original performance and pacing. It accepts MP3, M4A, and WAV uploads, with an effective direct-request limit of 200 MB and file duration of up to five hours. Results can be downloaded as MP3 files. Users can select Eleven Multilingual v2 or English v2 and adjust stability, similarity, style, speaker boost, noise removal, and transcript settings. The service runs on the web and is available through an asynchronous API: POST /v1/task/voice-changer returns a task_id for polling or webhook delivery. Listed uses include character voice replacement, consented localization, performance-preserving narration, and voice-style experiments. OpenSpeaker identifies ElevenLabs as its connected service and describes itself as an independent multi-provider AI workspace. Premium credits share one balance across voice, audio, music, image, and API workflows.
