Art of Crafting Natural Conversations

The Future is Spoken presents Jeff Adams as this week's guest. Jeff has been leading prominent speech & language technology research for more than 20 years. Until 2009, he worked at Nuance / Dragon, where he was responsible for developing and improving speech recognition for Nuance's "Dragon" dictation software. He presided over many of the critical improvements in the 1990s and 2000s that brought this technology into the mainstream and enabled widespread consumer adoption. After leaving Nuance, Jeff joined Yap, a company specializing in voicemail-to-text transcription. He assembled a strong team of 12 speech scientists who, within two brief years, were able to beat all competitors on an unbiased test set. They also matched the performance of a competitor who used (off-shore) human transcription. Yap's success caught the interest of Amazon, who wanted to jump-start their new speech & language research lab. Upon acquisition, Jeff led efforts to build one of the industry-leading speech & language groups. His Amazon team developed products such as the Echo, Dash, and Fire TV. Jeff left Amazon in 2014 to found Cobalt Speech and Language. Starting with their own experiences, they end up discussing crafting natural conversations for the bot. Tune in now!
