tts-narrator

Generate narration with Text-To-Speech technology

The input is a script file in YAML format. Example script files can be found under test/fixtures.

The script file is structured in this way:

• settings: script settings
  • voice: voice settings at script level
• chapters: array of chapter
  • each chapter can contain settings and multiple sections:
    • settings: chapter level voice settings that can override script level voice settings
    • sections: array of sections
      • each section can contain settings and multiple paragraphs:
        • settings: section level voice settings that can override upper level voice settings
        • paragraphs: array of paragraphs
          • each paragraph can contain settings and text:
            • settings: paragraph level voice settings that can override upper level voice settings
            • text: text content that needs to be converted into audio

The text field of a paragraph can be pure text, or an SSML fragment. Multi-line strings are supported.

It has command line flags --play and --no-play to control whether generated MP3s should be played back. This feature is supported by a dev dependency node-speaker. If you use it as a library in your project, and would like to have the play back capability, you need to install node-speaker as a dependency in your project.

When running on MacOS, to avoid illegal hardware instruction issue, try npm i speaker --mpg123-backend=openal

CLI

To use the CLI as an NPM package, you need to install it with all its optional dependencies, like this:

npm i -g --include=optional tts-narrator

DESCRIPTION
  Generate narration with Text-To-Speech technology

EXAMPLES
  $ tts-narrator myscript.yml --play --interactive --service azure --subscription-key-env TTS_SUBSCRIPTION_KEY --region australiaeast

  $ tts-narrator ./test/fixtures/script3.yml -s azure --ssml -r australiaeast --subscription-key-env=TTS_SUB_KEY  --no-play --interactive -d

  $ tts-narrator ./test/fixtures/script3.yml -s azure -r australiaeast --subscription-key-env=TTS_SUB_KEY --quiet

  $ tts-narrator ./test/fixtures/script3.yml

API

To use the NPM package as a dependency, you just need to install it normally, like this:

npm i tts-narrator

Example:

const ttsService = new AzureTtsService(...);
const ttsNarrator = new TtsNarrator(ttsService, './output-folder');
const script = await loadScript('./my-script.yml');
await ttsNarrator.narrate(script);
console.log(`One of the generated audio file is: ${script.chapters[0].sections[0].paragraphs[0].audioFilePath}`);
