Microsoft is making machine ears a little more attentive. Researchers from the tech giant have achieved an impressively low error rate for speech-recognition software.

The company hopes this milestone will help refine and personalize its AI assistant, Cortana, and features like Skype Translator.

Xuedong Huang, Microsoft’s chief speech scientist, said, the newest error rate of Microsoft’s conversational speech-recognition system achieved a word error rate (WER) of 6.3 percent, the lowest in the industry. Recently IBM announced an error rate of 6.6 percent.

 

Although Microsoft’s achievement is just 0.3 percent below IBM’s, incremental advancements bring machines closer to human-like capabilities. In speech recognition, the human error rate is around 4 percent.

Huang said, this new milestone benefited from a wide range of new technologies developed by the AI community from many different organizations over the past 20 years.

A few of these technologies include biologically inspired systems called neural networks, a training technique known as deep learning, and the adoption of graphic processing units (GPUs) to process algorithms.

Over the past two years, neural networks and deep learning have enabled AI researchers to develop and train systems in advanced speech recognition, image recognition, and natural language processing.

Last year, Microsoft created image-recognition software that outperformed humans. Although initially designed for computer graphics, GPUs are now regularly used to process sophisticated algorithms.
