Problems solved by technology

[0003] However, combining speech recognition technology and text translation technology for speech translation has the disadvantage of error accumulation. Wrong word gets wrong translation
It can be seen that errors in the speech recognition stage will accumulate in the text translation stage, resulting in inaccurate translation results. That is to say, the translation performance of the existing speech translation model needs to be improved

[0061] It should be noted that, the traditional voice translation method is usually to perform voice recognition on the voice first, recognize it as a text in the same language, and then process the recognized text, that is, use text translation technology to process the recognized text. Translate, translate it into text in another language, and realize voice translation. However, this traditional speech translation method often has the problem of error accumulation, that is, if an error occurs during speech recognition, the error will be accumulated in the subsequent text translation process, resulting in inaccurate translation results.

[0062] Therefore, in order to solve the above-mentioned defects, such as figure 1 The end-to-end speech translation model shown performs speech translation. The speech translation model includes an encoder, an attention layer (Attention) and a decoder. Through this speech translation model, the source language speech can not be speech recogn...

[0139] The above is a specific embodiment of a speech translation model training method provided in the first embodiment of the present application. Based on the speech translation model trained in the above embodiment, the embodiment of the present application also provides a speech translation method.

[0140] see Figure 8 , which shows a flow chart of a speech translation method provided by an embodiment of the present application, such as Figure 8 As shown, the method includes:

[0141] S801: Obtain a target voice to be translated.

[0142] In this embodiment, any speech translated by this embodiment is defined as the target speech. The language of the target speech is the same as that of the sample speech in the above-mentioned first embodiment.

[0143] It is understandable that the target voice can be obtained through recording according to actual needs. For example, the voice of a telephone conversation in people's daily life, or a recording of a meeting can be us...

Abstract

The invention discloses a training method and device for a speech translation model. The method comprises the steps that model training data including all pieces of sample speech is obtained, then translating is conducted on the obtained sample speech directly by means of a current speech translation model, and predicted translation text is obtained; meanwhile, by means of a current speech recognition model, the obtained sample speech is recognized, and predicted recognition text is obtained; then, according to the obtained predicted translation text and predicted recognition text, parametersof the speech translation model and the speech recognition model are updated. Due to the fact that the speech translation model and the speech recognition model share part of the model parameters, when the parameters of the speech recognition model are updated, the shared model parameters in the speech translation model can be updated, and then the model parameters of the speech translation modelare more accurate; therefore, when speech translating is conducted by means of the speech translation model, the translation performance of the speech translation model can be improved.

Description

technical field [0001] The present application relates to the technical field of speech translation, in particular to a method and device for training a speech translation model. Background technique [0002] Existing speech translation methods generally include two steps, ie speech recognition and text translation are implemented by speech translation models. Specifically, firstly, a piece of speech is recognized into a text in the same language through speech recognition technology, and then the recognized text is translated into a text in another language by using text translation technology, thereby realizing the speech translation process. [0003] However, combining speech recognition technology and text translation technology for speech translation has the disadvantage of error accumulation. Wrong words get wrong translations. It can be seen that the errors in the speech recognition stage will accumulate in the text translation stage, resulting in inaccurate transla...
