VI. Implement Speech To Text API<\/h2>\n

You can refer to this main API document\u00a0page<\/a><\/p>\n

Install the client library:<\/p>\n

composer require google\/cloud-speech<\/code><\/code><\/p>\n

Now you can use Speech-to-Text to transcribe an audio file to text.<\/p>\n

We will create a controller to handle 3 things:<\/p>\n

    \n
  1. Get the uploaded audio file from the request<\/li>\n
  2. Convert audio file to\u00a0FLAC<\/strong>\u00a0with library\u00a0FFMpeg<\/strong><\/a><\/li>\n
  3. Use the below code to show the text received from Speech-to-Text API<\/li>\n<\/ol>\n

    In SpeechToTextController:<\/p>\n

      \n
    1. Convert audio file received to\u00a0FLAC<\/strong>\u00a0from requests\"\"
      \nWhy conversion to FLAC is necessary?
      \n<\/strong>\u2013\u00a0All Speech-to-Text API synchronous recognition requests must include a speech recognition config field (of type RecognitionConfig).
      \n\u2013 encoding\u00a0 (required) specifies the encoding scheme of the supplied audio (of type AudioEncoding). If you have a choice in the codec, prefer a lossless encoding such as FLAC or LINEAR16 for best performance.<\/li>\n
    2. Show the text received
      \n\"\"<\/li>\n<\/ol>\n

      I create a\u00a0 template with only 1 input file named \u201cChoose File<\/strong>\u201c, a button submit named \u201cTranscribe<\/strong>\u201d and\u00a0a selection to select the language with default \u201cEnglish(US)<\/strong>\u201d<\/p>\n

      <\/p>\n

      We will choose a Japanese audio file.<\/p>\nhttps:\/\/briswell-vn.com\/wp-content\/uploads\/2020\/05\/japanese_file.mp3<\/a><\/audio>\n

      And this is the result:<\/p>\n

      \"\"<\/p>\n

      Great! It\u2019s works!<\/p>\n

      VII. Implement Text To Speech API<\/h2>\n

      You can refer to this main API document\u00a0page<\/a><\/p>\n

      Install the client library:<\/p>\n

      composer require google\/cloud-text-to-speech<\/code><\/p>\n

      Now you can use Text-to-Speech to create an audio file of synthetic human speech.<\/p>\n

      We will create a controller to handle 2 things:<\/p>\n

        \n
      1. Get the uploaded text file from the request<\/li>\n
      2. Use the below code to download an audio file received from Text-To-Speech API<\/li>\n<\/ol>\n

        In TextToSpeechController:<\/p>\n

          \n
        1. Prepare everything before conversion\"\"
          \nIn the image above, I can set some configures for the audio file before converting, such as\u00a0language,\u00a0voice,\u00a0gender,\u00a0speed<\/strong>\u2026<\/li>\n
        2. Download the audio file after conversion\"\"The audio file will be received with the MP3 extension.<\/li>\n<\/ol>\n

          Then I created a template for the Text-to-speech function. But this time, the template will be more detailed.\"\"<\/p>\n

          We will choose a Japanese text file<\/a>. And select the selections on the screen.\u00a0\"\"<\/p>\n

          This is the result:<\/p>\n

          \n
          \n
          \nhttps:\/\/briswell-vn.com\/wp-content\/uploads\/2020\/05\/text-to-speech-file.mp3<\/a><\/audio>\n<\/div>\n<\/div>\n<\/div>\n

          Awesome!!!<\/p>\n
