Deepgram has completed a $72 million Series B funding round, the largest raised by a speech AI company. The funds will be used to expand research and engineering teams, focusing on understanding and transforming speech at scale with end-to-end deep learning models. Deepgram's technology already offers fast, accurate, and cost-effective speech recognition, and the new features aim to provide more comprehensive insights into voice data, such as sentiment analysis, automatic summarization, speaker identification, and topic detection.
