Abstract

The invention discloses a speech recognition method and device, a related system and equipment, and a lexicon construction method, device and equipment. The speech recognition method comprises the following steps: determining a candidate pronunciation unit sequence of multilingual mixed speech data through a multilingual acoustic model; according to the first corresponding relation set, the second corresponding relation set and the third corresponding relation set, determining a first language text corresponding to a second language pronunciation unit in the candidate pronunciation unit sequence, and forming a candidate first language text sequence of the voice data; determining a first language score of the candidate first language text sequence through a language model of the first language; and according to the first language score and the third corresponding relation set, determining a multi-language mixed text sequence corresponding to the voice data. By adopting the processing mode, multilingual mixed reading speech recognition is carried out in a first language space decoding mode; therefore, the accuracy of multilingual mixed speech recognition can be effectively improved.

Description

technical field [0001] This application relates to the technical field of data processing, specifically to voice interaction systems, methods and devices, voice transcription systems, methods and devices, voice recognition methods and devices, lexicon construction methods and devices, ordering equipment, smart speakers, terminal equipment, and electronic equipment. Background technique [0002] With the advent of the era of artificial intelligence, a significant change is that more and more smart Internet of Things (IoT) devices appear in daily life, such as smart speakers, smart TVs, subway voice ticket machines, ordering machines and so on. The emergence of smart IoT devices greatly facilitates people's daily life, but also raises a question: how to interact with these devices more conveniently. Voice interaction is the most convenient way of interaction between people, so you can also choose voice interaction for how to interact with IoT devices. [0003] For an intelli...
