Write a greeting that sounds natural
Make numbers easy to understand
Enhanced text to speech interprets numbers based on context. Writing numbers out and adding pauses can help avoid unexpected pronunciation. Phone numbers| ✅ Do | ❌ Don’t |
|---|---|
| Write numbers phonetically with pauses, such as “two zero one… five five five… one two three four”. | Enter formatted numbers like “201-555-1234”. These may be read inconsistently. |
| ✅ Do | ❌ Don’t |
|---|---|
| Write “nine one one” instead of “911”. | Write “911”, which may be read as “nine hundred eleven”. |
| ✅ Do | ❌ Don’t |
|---|---|
| Keep options simple, such as “Press one for sales, two for support”. | Rely on typing numbers out if you need it pronounced a specific way. |
Control pacing with punctuation
Enhanced text to speech doesn’t support speech markup, but punctuation can still shape delivery.- Use ellipses (…) for longer pauses
- Use commas (,) for brief pauses
- Use periods (.) for full stops
Example
Thank you for calling… We’ll be right with you. Press one for sales, or stay on the line.
Handle names, acronyms, and special terms
If a word is mispronounced, try spelling it the way it sounds. For acronyms, spacing out letters often helps. Company names and acronyms| ✅ Do | ❌ Don’t |
|---|---|
| Write names phonetically if needed, such as “Kwo” instead of “Quo”. | Skip previewing your greeting to determine if you need to try spelling a word differently. |
| Space out letters for acronyms, such as “I T” instead of “IT”. | Keep letters together, as it may be read as a word. |
| ✅ Do | ❌ Don’t |
|---|---|
| Write write numbers as words, such as “Suite three hundred”. | Rely on numbers formatted as “1234” for building numbers or codes. |
| Spell out directions, such as “North Main Street” instead of “N Main St”. | Use shortened addressed like, “N Main St”. |
