performing a full text search of another data structure that stores extracted strings.

4. The computer program product of claim 1 , wherein the set of object properties include a duration of the first media file.

5. The computer program product of claim 1 , wherein the computer-readable instructions further comprise instructions for determining a determined attribute that includes a count of a number of times the extracted string appears in the set of text.

6. The computer program product of claim 1 , wherein the corresponding attribute that is extracted from the received set of text includes a time at which the extracted string appears in the first media file.

7. The computer program product of claim 1 , wherein storing the extracted string and corresponding attribute in the set of object properties comprises storing the extracted string and corresponding attribute as repeating properties of the first managed object.

8. The computer program product of claim 1 , wherein the computer-readable instructions further comprise instructions for:

storing a second file in the content management repository, the second file containing the extracted string and corresponding attribute; and

associating the second file with the first media file in the first managed object.

9. A system comprising:

a client computer comprising a client application executable to provide an interface between an end-user and a content management system;

a data store;

a server computer coupled to the client computer by a network, the server computer comprising code for:

providing the content management system, the content management system comprising a content management repository on the data store, the content management repository comprising a plurality of managed objects;

assigning, by the content management system, a unique identifier to a voice assistant device;

receiving, from the client application, audio data to be stored in the content management repository, the audio data associated with the voice assistant device;

converting, by an automatic speech recognition (ASR) processor, the audio data to a set of text that includes one or more attributes of the audio data associated with portions of the set of text;

in response to converting the audio data to the set of text:

accessing a configuration that specifies information to be extracted from text produced by the ASR processor, the configuration defining:

a set of target strings; and

one or more target attributes to determine for strings matching target strings from the set of target strings;

using the configuration:

extracting, by matching text from the set of text to a specified string defined in the configuration, an extracted string, wherein the extracted string matches the specified string defined in the configuration; and

extracting, from the set of text produced by the ASR processor and based on the configuration, a corresponding attribute of the extracted string, the corresponding attribute included in the one or more target attributes defined by the configuration;

storing a first media file containing the audio data in the content management repository as a first managed object owned by the voice assistant device, the first managed object comprising a set of object properties, including an object identifier (ID) of the first managed object, and the first media file;

configuring the first managed object to be searchable by the extracted string, wherein configuring the first managed object to be searchable by the extracted string further comprises:

storing the corresponding attribute of the extracted string in the set of object properties of the first managed object;

storing the corresponding attribute in the set of object properties of the first managed object; and
