The speech recognition industry is experiencing explosive growth, projected to reach $26.8 billion by 2025. AssemblyAI, a startup founded in 2017 by CEO Dylan Fox, is challenging established industry giants with its API for transcribing audio and video content. Backed by Y Combinator and NVIDIA, the San Francisco-based company leverages AI and machine learning to provide fast, accurate, and developer-friendly solutions.

Fox, with a background in business and self-taught programming skills, recognized the limitations of existing speech recognition technologies while working at Cisco. He envisioned an API, inspired by Twilio, that would offer superior accuracy and ease of integration. AssemblyAI’s platform uses deep learning models comparable to OpenAI’s GPT-3, providing features such as content summarization, search, indexing, and sensitive topic detection. Clients like CallRail, NBC, and The Wall Street Journal utilize AssemblyAI for call analysis, content transcription, and generating closed captions. AssemblyAI offers a consumption-based pricing model, scaling from cents per second to larger enterprise contracts. The company is experiencing rapid growth and plans to double its workforce to meet increasing demand.
