SpokenData API - Search in Speech

SpokenData API has a new function that enables users to search in recording transcriptions. This means that you can quickly get a list of captions matching the search query with their start and end time, caption content and speaker identity. The search can be performed either in all user recordings or in a list of selected recordings.

An example of a basic SpokenData search API call can be:

It simply means to search for occurrences of student in all recording transcriptions of the DEMO account.

The returned XML shows the elapsed time for parsing the search query and for performing the search. As the number of results can be very high, the search API call supports paging. By default, the maximum number of results per page is set to 10. In the output XML, there are 2 types of results - recordings and captions. Each has different paging.
