Google's AI can now translate your speech while keeping your voice

The new system, dubbed the Translatotron, has three components, all of which look at the speaker's audio spectrogram--a visual snapshot of the frequencies used when the sound is playing, often called a voiceprint. The first component uses a neural network trained to map the audio spectrogram in the input language to the audio spectrogram in the output language. The second converts the spectrogram into an audio wave that can be played.
