Phone numbers and order codes in an AI voiceover, kept clear

To keep a phone number or order code clear in a voiceover, write it in the script the way you want it spoken, in short groups with punctuation between them, and listen to that one sentence on its own. Decagon says its Chord model slows down on confirmation codes and phone numbers during live calls; with a script-based TTS job you control that in the text.

Write it as it should sound

A text-to-speech engine reads what it is given. Digits in one run can be read as a large number, a year, or a sequence. Spell the pattern out in the script.

• Group a phone number as 3-3-4 with commas or hyphens: 555, 010, 2030.
• Say the code letters and digits in chunks: A, 4, 7, then Q, 9.
• Put the number alone at the end of a sentence, so the voice finishes with it.
• Say the number twice if it matters, once in the voiceover and once on screen.
• Write currency in words if the engine reads symbols oddly, for example nine dollars and ninety-nine cents.

Test one sentence, not the whole script

Generate a short job with just the number sentence. Listen for ambiguity, then lock the wording and generate the full script.

The job record also stores the speed and generation settings that were used, or null when you sent none, so a later retake can match the first take.

Show it as well as say it

For a code a viewer must copy, add it as caption text or an on-screen card as well. Sume's caption job can burn authored cues with start and end times, so the code stays on screen for the time you set, and it reserves $0.20 for clips up to 60 seconds.

Never make the audio the only place a critical number appears.
