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.
Enterprise users with more complex customization requirements can submit requests 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 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.
- 2.Enter the word or phrase that should be read aloud differently (e.g. 'CO2')
- 3.Enter the alias for the word or phrase (e.g. 'carbon dioxide')
- 4.Select 'Add'
If you would like to edit or delete your alias, just use the icons on the right.

- 1.Use your mouse to highlight the word or phrase that should be read aloud differently (e.g. 'CO2')
- 2.Select 'Add alias'
- 3.Enter the alias for the word or phrase (e.g. 'carbon dioxide')
- 4.Select 'Apply to all instances in this project'
- 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'.
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.

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'.
Words and phrases are case-sensitive. For example, co2 will not trigger the alias for CO2. So, you may wish to create aliases for capitalized and uncapitalized versions of words.
Attached punctuation will be ignored. For example, CO2! will trigger the alias for CO2.
Here, you can manually update your text so that the alias is not triggered. Alternatively, you can delete the alias from the audio and then manually edit the text where it should apply.
