TechCrunch reports Oto’s voice-intonation tools for customer service
TechCrunch reported on December 17, 2019, that Oto had announced a seed round and was developing tools to help customer service operations interpret voice intonation. Co-founder and CEO Teo Borschberg said the company’s research drew on work at SRI International and on a database compiled from sales conversations. Oto described two products: a live coaching tool that gives customer service representatives feedback on how they sound during calls, and a tool that scores customer experience based on intonation. Borschberg said the coaching could help agents adjust their energy or respond to frustrated customers. He also described the score as a way to identify acoustic signatures associated with positive, neutral or negative reactions. The article reports Oto’s intended benefits, including better customer interactions, sales conversion and satisfaction scores; it does not provide evidence that the products achieved those results. Oto said it had customers using the product, while describing the effort as early. Whether intonation-based scores reliably reflect customer satisfaction, and how they perform across different callers and conversations, remains unresolved.
