Aliases (custom TTS rules)

Use aliases to add custom text-to-speech rules to your project.
You can create custom text-to-speech rules by adding an alias for any word or phrase. Wherever the word or phrase appears in your text, the AI voice will read the alias instead. This is helpful for expanding acronyms and abbreviations, providing pronunciations for sensational spellings, and creating text-to-speech shortcuts.
For more complex customizations, please send a request to [email protected]. Our text-to-speech engineers can prevent unwanted elements from being processed into audio, change default pause lengths, and more. You can also report voice issues.

Add an alias to a project

You can add an alias to a project so that it applies to every newly processed audio on the project. For example, let's say you're confident that 'CO2' should always be read as "carbon dioxide".
  1. 1.
    Go to the 'Settings (Aliases)' section of your project dashboard
  2. 2.
    Enter the word or phrase that should be read aloud differently (e.g. 'CO2')
  3. 3.
    Enter the alias for the word or phrase (e.g. 'carbon dioxide')
  4. 4.
    Select 'Add'
If you would like to edit or delete your alias, just use the icons on the right.

Or, if you are creating or editing audio in the TTS Editor:

  1. 1.
    Use your mouse to highlight the word or phrase that should be read aloud differently (e.g. 'CO2')
  2. 2.
    Select 'Add alias'
  3. 3.
    Enter the alias for the word or phrase (e.g. 'carbon dioxide')
  4. 4.
    Select 'Apply to all instances in this project'
  5. 5.
    Select 'Save changes'
All words or phrases with aliases will be highlighted purple in the TTS Editor. To edit or delete any alias, just highlight the word or phrase with your mouse then select 'Edit alias'.
The alias will be applied whenever audio is processed on this project. If you wish to update existing audios, you will need to reprocess them.

Add an alias to an audio

You can add an alias to a particular audio if you don't want it to be applied project-wide. For example, let's say you're usually happy with it being pronounced "NBA" but on this occasion you're writing about the National Boxing Association rather than basketball.
  1. 1.
    Start creating or editing your audio in the TTS Editor
  2. 2.
    Use your mouse to highlight the word or phrase that should be read aloud differently (e.g. 'NBA')
  3. 3.
    Select 'Add alias'
  4. 4.
    Enter the alias for the word or phrase (e.g. 'National Boxing Association')
  5. 5.
    Select 'Save changes'
All words or phrases with aliases will be highlighted purple in the TTS Editor. To edit or delete an alias (either at the project or audio level), just highlight the word or phrase with your mouse then select 'Edit alias'.
The alias will be applied when this audio is processed or reprocessed.
