Quick answer: A good bulk voice call script is short, written in plain spoken words, and asks for one thing. Say who is calling in the first few seconds, give the reason in one sentence, state the one detail the listener needs, and close with a single clear action. Read it aloud, play it on a phone speaker, and test it on a small batch before the full send.
Most voice campaigns that disappoint fail in the script, not the dialer. The call connects, the phone rings, and the person hangs up before the message has said anything useful. If you are new to the channel, start with our guide to what a bulk voice call service is and how it works in India. This article is only about the words.
Why a voice script is not a short email
A reader can skim, scroll back and read again. A listener cannot. The audio plays once, at your speed, to someone who was doing something else a second ago, often in a noisy place and sometimes on a basic phone. Long sentences, brackets, lists of options and links to click all work against you on a call.
Write for the ear. Use short sentences, common words, one idea per sentence, and numbers said the way people say them aloud.
The first five seconds
People decide quickly whether a recorded call is worth hearing. The opening has to answer two questions at once: who is this, and is it about me? Put the name of the organisation first, then the reason.
- Weak: "Hello, greetings, this is an important message for you."
- Better: "Namaste, this is Sunrise Dental Clinic. Your appointment is tomorrow at 11."
Skip the long welcome. If the first ten seconds could belong to any company, rewrite them.
One call, one ask
End every script with a single thing you want the listener to do: be at the clinic at 11, pay the fee by Friday, press 1 to confirm. Two asks split attention and the listener usually does neither. If you have a second message, send it as a separate campaign.
Some details do not suit a call at all. An address, a reference number or a link is hard to hold in memory. Our comparison of bulk voice calls and SMS marketing will help you decide which part of a message belongs on which channel.
Wording for listening
- Keep it short. Around 20 to 40 seconds of speech is a sensible starting point. That is a working guideline, not a rule, so test what your own audience stays on the line for.
- Repeat the one thing that matters. Say the date, time or amount once in the middle and once at the end. Repetition is tiresome on a page and helpful on a call.
- Say numbers the way you speak them. "Twelve hundred rupees", not "Rs. 1,200/-".
- Avoid abbreviations and codes. If the listener cannot picture it, they cannot act on it.
- Use the language people speak at home. A message in the listener's own language is understood faster than one in a second language.
Recorded voice or text-to-speech
Our bulk voice call service takes either a recorded audio file or a message generated by text-to-speech in several languages. A human recording sounds warmer and suits an announcement that goes to everyone unchanged. Text-to-speech is easier when part of the message changes from person to person, such as a name or an amount. Whichever you choose, listen to the final audio on an ordinary phone speaker, not on good headphones.
Adding a keypad option
If you want a reply, say the option plainly and only once: "To confirm, press 1." Do not offer five choices on an outbound call. The mechanics are covered in our guide to press-1 voice campaigns.
A template you can adapt
This is a made-up example for an appointment reminder. Change the details to suit your own business.
"Namaste, this is Sunrise Dental Clinic. This is a reminder that your appointment is tomorrow, Tuesday, at eleven in the morning. Please bring your earlier reports. To confirm, press 1. If you need to change the time, please call the clinic. Thank you."
Notice what it does. It names the caller first, gives the reason straight away, says the time once, makes one request, and offers one keypad option. It leaves out the address, the doctor's full name and the opening hours, because the patient already has them.
Test before you send
- Read the script aloud and time it.
- Play the audio on a normal phone speaker.
- Send to a small batch first, including a few colleagues' numbers.
- Check the call reports for how long people stayed on the line. Our guide to voice campaign reports and metrics explains what to look at.
Keep it compliant
A well-written script does not replace consent. Promotional calls should go only to people who agreed to receive them, and number lists need to be checked against the Do Not Disturb register. The details are in our summary of TRAI rules for bulk voice calls.
Frequently asked questions
How long should a bulk voice call script be?
About 20 to 40 seconds of speech is a reasonable place to start. Shorter is usually better, but there is no fixed figure. Test two lengths on small batches and compare how long people stay on the call.
Should I use a recorded voice or text-to-speech?
Use a recording for a fixed announcement that goes to everyone unchanged. Use text-to-speech when part of the message changes for each person, such as a name or an amount due.
Can I put a link or a phone number in the message?
A voice call cannot carry a clickable link. A phone number can be spoken, but say it slowly and twice, and keep it to one number. If the listener needs to copy something down, send it as a text message after the call.
Do I need to say who is calling?
Yes. It is good practice, and it is what makes people stay on the line. A call that does not say who it is from sounds like a nuisance call.
Can one script serve several languages?
Record a separate version in each language instead of translating word for word, and ask a native speaker to listen to each version before it goes out.
