Make your IVR voice over in three steps

01

Play the samples

Every voice reads the same line, so you compare voices, not scripts. Then paste your own script into the box at the top.

02

Copy a voice ID

Each voice has an ID. Copy the one you pick, or open it in the Playground to try more lines.

03

Generate the audio

Send each script to the text-to-speech API with that ID and save the files. When a line changes, regenerate that file only.

How to pick a voice for IVR voice over

Clear on a short prompt

IVR lines are four to ten words. The try-it box starts with a menu prompt, so listen for crisp word edges, because a menu option that blurs is a menu option callers miss.

Neutral enough to reuse

One IVR voice reads hundreds of prompts and every on-hold message. Pick one that does not get tiring on the fiftieth hearing.

Fits the line, not just the studio

IVR audio plays over a phone line, so test your shortlist on a real call before you generate the whole menu tree.

Use Jane's voice ID in a request

Every voice here has an ID. Pass it as the voice parameter of a text-to-speech request, and swap in any other ID from the list.

FAQs

What is IVR voice over?

IVR voice over is the voice a caller hears in a phone menu: the greeting, the menu options and the on-hold messages. With an AI voice, you generate each prompt from text with one voice ID instead of booking a voice actor.

Can I use this as an IVR voice generator and keep the files?

Yes. Send each prompt to the text-to-speech API with the same voice ID and save the audio. Use the same ID for later prompts so the menu keeps one voice.

How do I make an IVR voice recording in the format my phone system needs?

Set the output format in the text-to-speech request. Ask for raw mu-law at 8 kHz for a phone line, or a WAV file at the sample rate your phone system lists, then upload it as the prompt.

Can I record on-hold messages with these voices?

Yes. Write the on-hold message as text and generate it with the same voice as your menu, so callers hear one voice from the greeting to the hold queue.

Should an IVR use a recorded actor or an AI voice?

An AI voice lets you change a prompt the same day, with no studio session. Listen to the samples here and decide whether one of them fits.

Is there an alternative to a menu at all?

Yes. A customer support agent lets callers say what they need instead of pressing a key.
