What is an interactive voice response (IVR) survey?
At Surveys Australia we use IVR as part of our multi modal approach to fieldwork. It is layered onto email, SMS, and CATI to lift overall reach and response, not used as a substitute for live interviewing. Where a project calls for interviewer rapport, probing, or complex questioning, CATI remains our primary phone mode. IVR is deployed where it will add reach or efficiency without compromising data quality.

IVR is best understood not as a standalone survey mode, but as a phone-based amplifier for the rest of your campaign. It adds reach at exactly the point where email and CATI are losing ground.
Email invitations are losing reach as inbox filtering, tab sorting, and outright screening reduce the odds that a survey invitation is even seen.
CATI response rates are falling as respondents and telcos increasingly block or screen unknown numbers.
IVR gives you a low cost way to reach respondents by phone and hand them off to the channel most likely to convert. A voicemail can prompt them to check their inbox for the survey link, and a "press 2 to receive an SMS" option delivers the survey link straight to their phone in the moment they are already engaged.
SMS delivery is where much of the value sits. Open rates for SMS remain good, so converting a phone contact into an SMS delivered survey link is often the single most effective response driver in the campaign.
Voicemail reminders are cheap, unintrusive, and reinforce the other modes without requiring the respondent to answer the call.
For short structured surveys, respondents can also complete the survey directly on the keypad, giving a further response pathway alongside SMS and email.
IVR is automated and scalable, which makes it materially cheaper per contact than CATI while still using the phone channel to reach respondents.
Every respondent hears the same script delivered the same way, which supports data consistency and reduces interviewer effects.
IVR complements your existing modes rather than replacing them. You continue running email and CATI, and layer IVR on top to lift overall reach and response.
Ability to access respondents across Australia, including hard-to-reach populations.
Your survey data is protected under ISO 27001 standards and Australian privacy regulations.

IVR earns its place in a multi modal design when it can convert a phone touchpoint into a completed response through another channel, or when a low cost phone reminder will lift response to the wider campaign.
When email open rates are soft and a phone touchpoint is needed to prompt respondents to check their inbox or open an SMS link.
When the sample is mobile heavy, so the "press 2 for SMS" pathway is likely to convert well and deliver the survey link into a channel with high open rates.
When CATI response rates alone will not deliver the required completes within budget, and an additional low cost contact mode is needed to hit fieldwork targets.
When reminder or re-engagement waves are needed for respondents who have received an invitation but have not yet responded. A voicemail is a cheap, scalable way to nudge them back to the survey.
When the survey itself is short and structured, with closed questions that can be answered comfortably on a keypad, so keypad completion becomes a viable third pathway alongside SMS and email.
When the target population is more likely to listen to a voicemail than to answer an unknown number, which increasingly describes most demographics.
