Dear Fellow Scholars, this is Two Minute Papers with Károly Zsolnai-Fehér. Today we are going to listen to some amazing improvements in the area of AI-based voice cloning. For instance, if someone wanted to clone my voice, there are hours and hours of my voice recordings on Youtube and elsewhere, they could do it with previously existing techniques... Read More

Questions & Answers

Q: How much speech data is needed for AI voice cloning using this new technique?

Only 5 seconds of speech data is required for the AI system to clone someone's voice.

Q: What are the three components involved in this AI-based voice cloning technique?

The three components are the speaker encoder, which learns from thousands of speakers; the synthesizer, which converts text into a Mel Spectrogram; and the neural vocoder, which generates a waveform as an output.

Q: How is the naturalness and similarity of the cloned voice measured?

The paper discusses evaluating the naturalness and similarity using mean opinion scores, which assess how well the cloned voice passes as genuine human speech.

Q: What is the importance of data training and fitting the different puzzle pieces together?

The choice of training data and the way the three components are combined greatly affect the naturalness and similarity of the cloned voice, making them crucial factors in the voice cloning process.

Summary & Key Takeaways

• Previously, voice cloning required hours of voice recordings, but this new technique can clone voices with just 5 seconds of speech data.

• The system uses a speaker encoder, synthesizer, and neural vocoder to learn the essence of human speech and generate a waveform as an output.

• Evaluating and measuring the naturalness and similarity of the cloned voice is a challenge, but the paper provides detailed explanations and evaluation methods.
