Select 'Schedule for later' then enter a date and time (optional — scheduling means that your audio will not be published until the scheduled time)
Select 'Process audio'
Your text will now be processed into audio. This will use characters. Processing should only take a few minutes — you can check the audio's status in the 'Content (Audios)' section of your project dashboard.
Can I insert my own audio into my text-to-speech audio?
Can I save my draft and come back to it later?
Can I edit my text and reprocess the audio?
Can I automatically embed audio into my website or app?
