Google’s Tacotron 2 and WaveNet


Google’s AI research division has developed two powerful neural networks for generating natural sounding speech: Tacotron 2 and WaveNet. These models can produce human like voices for digital assistants and other applications.

Tacotron 2 converts text into spectrograms, the visual representation of speech. It then uses those spectrograms to generate raw audio waveforms. The result is speech that sounds more natural than typical text to speech systems.

WaveNet, on the other hand, is a neural network that generates raw audio waveforms. It uses a novel architecture that can model any distribution of data, including speech. When combined with Tacotron 2, WaveNet helps produce speech that mimics the prosody, pronunciation, and articulation of human voices.

Together, Tacotron 2 and WaveNet have enabled huge leaps in the realism of synthesized speech. Systems built on these models can generate voices that sound nearly indistinguishable from humans. Some companies are already using them to create digital assistants with natural as well as engaging voices.

The possibilities for AI generated speech are endless. It could be used for audiobooks, podcasts, voiceovers, and more. However, bad actors could also misuse this technology to generate synthetic media and carry out fraud. Regulations may be needed to prevent potential issues, even as companies continue improving these models to build the digital assistants of the future.

Overall, Tacotron 2 and WaveNet represent a massive breakthrough in speech synthesis. They’ve given rise to voices that sound human yet are completely artificial a trend that looks set to accelerate in the coming years. The age of truly conversational AI may be just around the corner.
