Abstract

The invention discloses a voice phoneme recognition method, a voice phoneme recognition device, a storage medium and an electronic device. The method comprises the following steps: extracting a plurality of first voice features from a plurality of voice frames by using a shared coder; determining a plurality of key voice features from the plurality of first voice features by using a CTC model, wherein each key voice feature corresponds to a peak position output by the CTC model; determining a voice feature set corresponding to each key voice feature, wherein each voice feature set comprises acorresponding key voice feature and one or more voice features adjacent to the corresponding key voice feature in the plurality of first voice features; carrying out feature fusion on the voice features in each voice feature set by using self-attention network, thus obtaining a plurality of fused voice features, wherein each voice feature set corresponds to one fused voice feature; and recognizingthe phoneme corresponding to each fused voice feature in the phoneme set by using a coder of a target attention model.

Description

[0001] This application is a divisional application of the original application with the application number: 2019105787247, the application date: June 28, 2019, and the invention name is "Speech phoneme recognition method and device, storage medium and electronic device". technical field [0002] The invention relates to the field of computers, in particular to a speech phoneme recognition method and device, a storage medium and an electronic device. Background technique [0003] At present, in acoustic model modeling, the end-to-end modeling method mainly used is a frame-level feature coding method, for example, a CTC (Connectionist Temporal Classification, connection temporal classification) model. This method has a condition-independent assumption (that is, the current output is only related to the input features, and has nothing to do with the historical output). [0004] However, due to the correlation between speech data, although the above-mentioned condition-independ...
