And there are numerous Youtube videos that show how quick fixes can be made using text-to-speech applications. Today, things couldn’t be more different, and vocal models are convincing enough for overdubbing narration mistakes in recorded audio. And the highly compressed output, necessary due to memory constraints, limited the market to niche applications. Early digital voices had their origins in silicon designs such as Voice Synthesis Processor (VSP) LPC10 decoding chips produced by Texas Instruments towards the end of the 1970s and into the 1980s.
Having access to high-quality digital voices enables firms to engage audiences in a way that just wasn’t possible in the early days of computer-generated speech. Silbert and Uri Hassonc, based at Princeton University, US, in a study dubbed Speaker–listener neural coupling underlies successful communication. “Such neural coupling substantially diminishes in the absence of communication, such as when listening to an unintelligible foreign language,” write researchers Greg J. Under the hood, there’s a lot happening to turn text inputs into spoken words that no longer sound robotic and are much more appealing to humans.Īnd the payback begins with much greater coupling in the brain of the listener when voices are well understood. Synthetic voice trend amps up sonic brandingĭeep learning and, more recently, generative AI tools have poured rocket fuel onto voice synthesis and the resulting computer-spoken audio is now eerily believable.
