Rev.ai
Rev.ai was built by leading speech recognition experts from millions of hours of accurate human-transcribed content. We began in 2011 with Rev.com, providing human transcription services. We are now the world's largest transcription vendor, with over 35,000 contractors who transcribe millions of minutes of audio each month. In 2017 we launched Temi, an automated speech-to-text transcription and editing service. Temi has already transcribed 20 million minutes of content and was named the best transcription service by Wirecutter. Today our best-in-class speech engine is available to everyone as Rev.ai. We're helping companies get the most out of their audio and video content by making it searchable and accessible. -

Voci
Medallia
Companies engage with customers by phone more than any other channel, and these interactions represent a gold mine of untapped information. Listening to every customer call is costly and time-consuming and not physically practical. As a result, only a fraction of randomly selected calls is typically reviewed. These voice interactions reveal the true voice of your customers and enable you to get to the heart of their concerns. With our highly accurate, automated speech-to-text transcription, you can transform your unstructured voice data into transcripts that can be integrated into your analytics platforms. Voci enables you to improve agent quality monitoring, enhance the customer experience, extract competitive intelligence and ensure compliance. -
