AI Voice Changer with Speech to Speech

Speech-to-speech (STS) voice changing transforms your actual voice recording into a different voice while preserving your emotions, timing, and expression. Unlike text-to-speech which generates speech from text, STS takes your real voice as input and outputs it in a completely different voice - like a celebrity or movie character - while maintaining all the emotional nuances of your original recording.

Our AI analyzes the emotional content of your speech - including pitch variations, speaking pace, intensity, and subtle vocal cues that convey emotion. When transforming your voice, these emotional markers are preserved and applied to the target voice. So if you record yourself laughing, the output will sound like the celebrity laughing with the same timing and intensity.

Voices AI supports all common audio formats including MP3, WAV, M4A, AAC, and FLAC. For video files, we support MP4, MOV, AVI, and MKV. When you upload a video, our AI automatically extracts the audio track, transforms it, and you can download the transformed audio separately.

Yes! With our voice cloning feature, you can create a custom target voice from any audio sample. Record 30-60 seconds of someone speaking and our AI will create a voice clone that can be used as a transformation target. This is perfect for creating custom character voices or preserving a specific person's voice.

Processing is very fast - short clips transform in seconds. Our AI is optimized for speed while maintaining high quality output. You'll see a progress indicator and be notified when your transformation is complete.

Basic voice filters and pitch shifters simply modify your existing voice with effects. Our AI speech-to-speech technology completely transforms your voice into a different person's voice while maintaining your emotional expression. The output sounds like a real person speaking, not like a filtered version of your voice.

Voices AI offers over 300 target voices including celebrities like Morgan Freeman, Elon Musk, and Emma Watson, politicians like Trump and Obama, movie characters like Venom and Ghostface, anime characters, and professional voice actors. We continuously add new voices based on user requests.

Yes! Voices AI is perfect for content creation. Many creators use our voice changer for YouTube videos, TikTok content, Instagram Reels, and other social media. The output is high-quality and ready for professional use. Please review our terms for specific guidelines on celebrity voice usage.

You can record or upload audio clips of various lengths. Shorter clips process faster, while longer recordings may take a bit more time. For best results with long content, we recommend breaking it into smaller segments.

Speech-to-speech works best with spoken content. For singing, the AI will transform the voice but musical elements may vary in quality. For AI music creation with celebrity voices, check out our AI Songs feature which is specifically designed for music.

Currently Voices AI is available as a mobile app for iOS and Android. This lets you record directly on your phone and create content on the go. Desktop support may be added in the future.
