Audio Data Collection

What is Audio Data Collection?
Audio data collection describes the process of gathering and measuring audio data from a variety of sources. In order for virtual assistants and automatic speech recognition (ASR) systems to recognize human speech, they need to first be exposed to large quantities of high-quality audio data.

While the human brain can process a wide range of sounds effortlessly, teaching a machine to recognize audio input is a much more arduous task. All audio-based machine learning systems rely on a foundation of relevant and diverse audio training data in order to function correctly. Lionbridge collects audio data to develop, calibrate, and improve voice-enabled applications for the world’s largest corporations. Working with Lionbridge unlocks access to a network of 500,000+ qualified linguists, in-country speakers, and experienced project managers capable of collecting audio data for a range of use cases.
