如何在 Jitsi Meet 中启用转录功能

本文将介绍如何在 Jitsi Meet 中启用转录功能。

安装和配置

要通过转录安装和配置 Jitsi Meet，请执行以下操作：

1. 根据文档安装 Jitsi Meet。

2. 安装 Jigasi，Jitsi Meet 服务可与语音转文本服务对接，提供转录功能：

sudo apt install jigasi

3. 配置 Jigasi。

配置在 /etc/jitsi/jigasi/sip-communicator.properties 文件中完成。取消注释并编辑以下几行：

# Options regarding Transcription. Read the README for a detailed description
# about each property

org.jitsi.jigasi.ENABLE_TRANSCRIPTION=true

...

# delivering final transcript
org.jitsi.jigasi.transcription.DIRECTORY=/var/lib/jigasi/transcripts
org.jitsi.jigasi.transcription.BASE_URL=http://localhost/
org.jitsi.jigasi.transcription.jetty.port=-1
org.jitsi.jigasi.transcription.ADVERTISE_URL=false

# save formats
org.jitsi.jigasi.transcription.SAVE_JSON=false
org.jitsi.jigasi.transcription.SAVE_TXT=true

# send formats
org.jitsi.jigasi.transcription.SEND_JSON=true
org.jitsi.jigasi.transcription.SEND_TXT=false

# Vosk server
org.jitsi.jigasi.transcription.customService=org.jitsi.jigasi.transcription.VoskTranscriptionService
# org.jitsi.jigasi.transcription.vosk.websocket_url={"en": "ws://localhost:2700", "fr": "ws://localhost:2710"}
org.jitsi.jigasi.transcription.vosk.websocket_url=ws://localhost:2700

4. 启动Vosk：

docker run -d -p 2700:2700 alphacep/kaldi-en:latest

5. 配置 Jitsi Meet。

其配置文件名会因安装 Jitsi Meet 时配置的主机名而异。我的文件位于 /etc/jitsi/meet/omoiomoi.org-config.js。您需要编辑配置文件的以下部分：

   // Transcription options.
    // transcription: {
    //     // Whether the feature should be enabled or not.
    //     enabled: false,

    //     // Translation languages.
    //     // Available languages can be found in
    //     // ./src/react/features/transcribing/translation-languages.json.
    //     translationLanguages: ['en', 'es', 'fr', 'ro'],

    //     // Important languages to show on the top of the language list.
    //     translationLanguagesHead: ['en'],

    //     // If true transcriber will use the application language.
    //     // The application language is either explicitly set by participants in their settings or automatically
    //     // detected based on the environment, e.g. if the app is opened in a chrome instance which
    //     // is using french as its default language then transcriptions for that participant will be in french.
    //     // Defaults to true.
    //     useAppLanguage: true,

    //     // Transcriber language. This settings will only work if "useAppLanguage"
    //     // is explicitly set to false.
    //     // Available languages can be found in
    //     // ./src/react/features/transcribing/transcriber-langs.json.
    //     preferredLanguage: 'en-US',

    //     // Disable start transcription for all participants.
    //     disableStartForAll: false,

    //     // Enables automatic turning on captions when recording is started
    //     autoCaptionOnRecord: false,
    // },

取消注释并编辑相应行，如下：

    // Transcription options.
    transcription: {
    //     // Whether the feature should be enabled or not.
        enabled: true,

    //     // Translation languages.
    //     // Available languages can be found in
    //     // ./src/react/features/transcribing/translation-languages.json.
    //     translationLanguages: ['en', 'es', 'fr', 'ro'],

    //     // Important languages to show on the top of the language list.
    //     translationLanguagesHead: ['en'],

    //     // If true transcriber will use the application language.
    //     // The application language is either explicitly set by participants in their settings or automatically
    //     // detected based on the environment, e.g. if the app is opened in a chrome instance which
    //     // is using french as its default language then transcriptions for that participant will be in french.
    //     // Defaults to true.
        useAppLanguage: true,

    //     // Transcriber language. This settings will only work if "useAppLanguage"
    //     // is explicitly set to false.
    //     // Available languages can be found in
    //     // ./src/react/features/transcribing/transcriber-langs.json.
    //     preferredLanguage: 'en-US',

    //     // Disable start transcription for all participants.
    //     disableStartForAll: false,

    //     // Enables automatic turning on captions when recording is started
    //     autoCaptionOnRecord: false,
    // },

6. 重新启动所有 Jitsi Meet 服务：

sudo systemctl restart jitsi-videobridge2.service
sudo systemctl restart jicofo.service
sudo systemctl restart jigasi.service
sudo systemctl restart prosody.service
