Marco Liuni is the co-founder and audio miner at Alta Voce, a research-backed startup based in Paris, France that shapes the emotions in human and artificial voices to enhance communication.

Their product, Alta Call, is a voice transformation technology for contact centers, improving both the clarity of speech and enhancing the smile in the voice. Marco explains how their tech works, and we hear samples of audio that have been transformed.

We also cover some of the ethical issues of transforming human voice, and how they are tackling this in the product. Marco shares his advice for newcomers to the field of speech transformation, and some of his recommended reading.

Highlights

  • A/B testing allows the call center and Alta Voce to measure the improvement in KPIs, and iterate on the product.

  • Voice is key to a person’s identity and must be respected.
  • Alta Voce strives to only enhance the emotions already in the voice; they don’t add new emotions.
