Automatic Speech Recognition: A Sound Innovation - Digital Marketing Content Services

Momentum for ASR picked up through the 80s, giving rise to practical speech recognition operations such as Dragon Dictate in 1990. AT&T Inc. used this technology for their Recognition Processing Service to route calls without the use of an operator. During this decade, ASR vocabulary grew from a few hundred words to several thousand. Innovators developed a new ASR method in the 90s thanks to big data and faster computers: End to End Deep Learning ASR. This method allowed for "learning" and "training" to improve accuracy as more information is fed into networks.
