Custom external lexcion does not work when calling TTS speech synthesis service using Java SDK

xin chen 0

We don't want the * sign to sound, so we set up a custom lexicon, but the synthesized speech doesn't seem to be affected by the lexicon.

<speak xmlns="http://www.w3.org/2001/10/synthesis"
       xmlns:mstts="http://www.w3.org/2001/mstts"
       xmlns:emo="http://www.w3.org/2009/10/emotionml"
       version="1.0"
       xml:lang="zh-CN">
    <voice name="zh-CN-XiaoxiaoNeural" style="chat" rate="5%%">
        <lexicon uri="https://guiyaai.blob.core.windows.net/tts-resources/azure_custom_lexicon.xml"/>
         **测试**##BTW和

I tested it on Speech Studio and found that in order to make '*' not sound, you should use '-' instead of 'sli'. Using 'sli' cannot save Lexion, which I accidentally tested. What is the correct configuration recommended by the official document for not allowing a certain symbol or word to be pronounced? Can you provide a correct example? After testing on Speech Studio, I corrected the previous error with Lexcion, but it still doesn't work when calling speech synthesis through SDK.

Here is my Lexion configuration on Speech Studio:

<?xml version="1.0" encoding="utf-8"?> <lexicon xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.w3.org/2005/01/pronunciation-lexicon http://www.w3.org/TR/2007/CR-pronunciation-lexicon-20071212/pls.xsd" version="1.0" alphabet="sapi" xml:lang="zh-CN" xmlns="http://www.w3.org/2005/01/pronunciation-lexicon"> <lexeme> <grapheme>BTW</grapheme> <alias>By the way</alias> </lexeme> <lexeme> <grapheme>你好</grapheme> <phoneme>ni 2 - hao 3</phoneme> </lexeme> <lexeme> <grapheme>*</grapheme> <phoneme>-</phoneme> </lexeme> </lexicon>

I have resolved this issue mainly by uploading custom Lexion files in Speech Studio, as Speech Studio has a built-in strict Lexion file verification program. If the file format is incorrect, the upload will fail, and the report information can be downloaded to adjust the Lexion content. After successful upload, it indicates that the Lexion file is correct.
