Microsoft Research announced it had matched human accuracy in recognizing conversational speech. Its word error rate on the industry-standard Switchboard task was 5.9%, about the same as professional transcribers given the same conversations and the best figure recorded at the time; it later improved to 5.8%, edging slightly past the human benchmark. Accumulated progress in deep learning had closed one of the gaps long assumed to favor humans. It is not a generative AI result, but it shows the weight Microsoft placed on speech recognition as a research area at the time.
