How to enable Voice+ in the inca platform?

Voice+ is available to all platform users but to enable Voice+ on the portal, users are required to contact the inca team and update their MSA as users need to agree to all terms related to personal data collection (PII). 

Once this has been done, users can proceed to their project (Question Builder), and on the Overview page, toggle on the Enable Voice+.

Default Input Types

A new drop-down will show and users can select the input type (i.e. Text, Audio, Photo, Video, File Upload) or the allowed responses that participants can make to the open-ended question.

To enable Voice responses, select Audio in the drop-down. To enable Video responses, select Video in the drop-down.

Default Preferred Input Type

This will be the default response or input type when the participant answers your open-ended question in the chatbot. If the Text input is selected as default, participants can still answer in different ways based on what is enabled on the Default Input Types

Project Level Input Types

Please note that the selected input types on the Overview page will be the allowed responses for all open-ended questions in the entire survey, but users can still modify it at a question level. In the example above, the input responses allowed at the project level are Text, Audio, and Video.

In the example below, users can override this for each open-ended question that users would like to modify. In your open-ended Question Editor, go to the Question Settings and toggle the Custom Input Type (i.e. allowing Text and Video response only) and select the preferred Default Input Type(i.e. Video answer as default in the chatbot, but Text response is still allowed)

Auto Send Response for Video or Voice 

By default the auto send feature is enabled for all open end questions with Voice+ enabled.




In the survey chatbot, this allows allows participants to answer more seamlessly by clicking the mic or video button and clicking "Tap to start recording" and "Tap to stop recording and submit"





The video or voice will be processed and will be auto submitted as a new response. As a participant answering the survey, they can can still review and edit their voice or video recording even though the auto send is enabled by clicking the pencil button. 


As a best practice, we also recommend users to add an instruction after the first OE to let participants know they can still review and edit their voice or video recording even though the auto send is enabled, e.g. the following:
If you answer by voice or video and you want to change your answer or in case your recording wasn’t captured properly, you can click the pencil icon to delete your previous answer.

When can I disable the auto submit video/voice recordings?
If you’d like to have multiple response/clips for a single open end question, users can disable the “auto submit” toggle. In the survey chatbot, after participants have stopped recording of the current response/clip, they can decide if they want to record another one or submit (arrow icon).

Participants can record as many responses/clips they want for a single open end question before they click submit. 




How to access the audio and video responses?

There is a real-time transcription of voice and video responses and these will be turned into verbatim responses as output in the Dashboard, similar to text responses.

To download the audio and video files, go to the Dashboard, and on the Data page, click Batch Export Multimedia Data. Users will be able to download a zip file containing all the multimedia inputs (Audio, Video, Photos) from participants for all the open-ended questions.
