Title: Innovations of David Qiu in Speech Recognition Technology
Introduction
David Qiu is an accomplished inventor based in Brookline, MA (US). He has made significant contributions to the field of speech recognition technology, holding a total of 3 patents. His work focuses on enhancing the accuracy and efficiency of automated speech recognition systems.
Latest Patents
One of David Qiu's latest patents is titled "Multi-task learning for end-to-end automated speech recognition confidence and deletion estimation." This method involves receiving a speech recognition result corresponding to a transcription of an utterance spoken by a user. For each sub-word unit in a sequence of hypothesized sub-word units, a confidence estimation module is utilized to obtain a respective confidence embedding. This process generates a confidence feature vector, an acoustic context vector, and a respective confidence output score for each sub-word unit. Ultimately, the method determines an utterance-level confidence score for the transcription based on these scores.
Another notable patent is "Context-aware neural confidence estimation for rare word speech recognition." This automatic speech recognition (ASR) system includes an ASR model, a neural associative memory (NAM) biasing model, and a confidence estimation model (CEM). The ASR model encodes a sequence of audio frames into higher-order feature representations, while the NAM biasing model modifies these representations based on contextual information. The CEM computes the confidence of the final speech recognition result output by the decoder, enhancing the overall performance of the system.
