WE SUPPLY THE WORLD'S LEADING COMPANIES WITH DATA FOR NATURAL LANGUAGE PROCESSING
WHAT IS AUTOMATIC SPEECH RECOGNITION?
Automatic speech recognition (ASR) is the technology that converts spoken word into text. In other words, ASR is the first step in enabling voice-activated applications to process speech. Like other natural language processing applications, ASR systems require a wealth of diverse training data. Speech samples need to be collected from a broad range of participants and environments for ASR systems to correctly recognize, process, and respond to voice commands.
At Lionbridge, we have decades of experience in collecting natural language data to train ASR technology. Using our network of 500,000+ qualified contributors, we can help you to cover all possible scenarios and languages that an automatic speech recognition system might encounter in the real world.
