IVR & phone system voice prompts
Generate professional call-flow prompts for VoIP, PBX, and contact centers — menu trees, queue messages, and after-hours scripts.
IVR voice prompts are the spoken menus, queue messages, and after-hours announcements callers hear on a phone system. MachenVoice lets IT and ops teams draft each branch as a block, generate neutral neural speech, and upload MP3 files to Twilio, Asterisk, or your CPaaS portal.

How to do it step by step
- 1
List every menu branch and queue state on paper; assign one MachenVoice block per prompt file you will upload.
- 2
Pick Ryan (English - United Kingdom) or Aria (English - United States) for US/UK menus and keep the same voice across the tree.
- 3
Write “Press” instructions with commas before digits: “For sales, press 1.” Preview to ensure digits are not swallowed.
- 4
Generate each block, export MP3, and name files consistently (`main-menu_v3.mp3`).
- 5
Upload to your PBX or CPaaS, transcode to G.711 if required, and place test calls from mobile and landline handsets.
Tips for natural-sounding telephony prompts
- Use short sentences; callers are multitasking and may be on speakerphone.
- Say “press” before the digit, not after, and avoid stacking multiple options in one breath.
- For URLs, say “visit our website” unless marketing requires spelling a short domain you have tested.
- Keep hold messages under twenty seconds before repeating; chain multiple blocks in the PBX if needed.
- Avoid emotional language in emergency or outage scripts—state facts and next steps calmly.
Which voice should I choose?
| Voice | Why it fits this use case |
|---|---|
| Aria (English - United States) | US English main menus and promotional queues. |
| Guy (English - United States) | Slightly deeper US prompts for utilities and healthcare IVR. |
| Ryan (English - United Kingdom) | UK English call centers and nationwide hotlines. |
| Sonia (English - United Kingdom) | UK English after-hours and callback instructions. |
| Francisca (Portuguese - Brazil) | Brazilian Portuguese customer service trees. |
| Elvira (Spanish - Spain) | European Spanish IVR when agents are Spain-based. |
Common mistakes
One giant block for the entire phone tree.
Split per branch so marketing can update sales hours without regenerating support prompts.
Uploading MP3 without testing mobile codecs.
Transcode to G.711 μ-law or A-law when your carrier requires it; verify clarity on cell networks.
Using jargon callers do not say aloud.
Replace internal product codenames with the words customers use on tickets.
Forgetting holiday overrides.
Store seasonal prompts as separate files and document PBX effective dates alongside MP3 versions.
Recording queue wait times that change every minute.
Use a generic range (“about five minutes”) or rotate pre-recorded clips on a schedule instead of regenerating TTS hourly.
FAQ
- Which codec should I use?
- MachenVoice exports MP3 at 24 kHz mono. Transcode to G.711 or Opus in your PBX or CPaaS if your carrier requires it.
- Which voice works for US IVR?
- Aria (English - United States) and Guy (English - United States) are common choices—preview your menu script before bulk upload.
- Who is responsible for legal disclaimers?
- You write and approve scripts; MachenVoice provides synthesis only. Legal review stays on your side.
- Can I generate prompts in multiple languages?
- Yes—duplicate blocks per language and pick voices from the catalog for each locale.
- How fast can we iterate?
- Edit text, regenerate the affected block, and upload a new MP3—no studio scheduling for minor wording changes.
