关于此工作流
This ComfyUI workflow performs voice conversion using the ElevenLabs Speech-to-Speech API. You provide a source audio clip (via LoadAudio or RecordAudio), choose a target voice (via ElevenLabsVoiceSelector for a preset voice or ElevenLabsInstantVoiceClone to create a new clone), and the ElevenLabsSpeechToSpeech node generates a new recording that preserves the timing and content of the original while changing the vocal timbre to match the selected voice. The output can be saved with SaveAudioMP3 or SaveAudioOpus.
Technically, the pipeline routes your source waveform into ElevenLabsSpeechToSpeech along with a target voice ID. In Option 1, ElevenLabsVoiceSelector queries your ElevenLabs account and outputs a selected voice for direct use. In Option 2, ElevenLabsInstantVoiceClone uploads a clean reference sample and returns a new voice resource that is then fed into the Speech-to-Speech node. The Note node contains guidance, and several nodes are initially bypassed so you can enable only what you need. This design makes it easy to A/B between preset voices and instant clones while keeping file management simple with explicit save nodes.
常见问答
Yes. The ElevenLabsVoiceSelector, ElevenLabsInstantVoiceClone, and ElevenLabsSpeechToSpeech nodes call the ElevenLabs API. Add your API key to the nodes or ComfyUI’s configuration as instructed in the Note node.
Use clean, single-speaker recordings with minimal background noise and reverb. Aim for steady levels without clipping, and avoid music. A clear 30–60 second sample is typically enough for Instant Voice Clone.
SaveAudioMP3 produces a widely compatible file ideal for general distribution. SaveAudioOpus yields smaller files at similar perceptual quality—useful for web or app playback—though some workflows may require MP3.
Yes. Audio for voice selection, cloning, and speech-to-speech is processed by ElevenLabs’ servers via their API. Review ElevenLabs’ terms, privacy policy, and your usage limits on their dashboard.
