You can use the Audio feature to transcribe individual audio documents or multiple audio documents. After the documents are transcribed, you can search for, review, redact, and produce audio documents.
Note: Your administrator must configure and enable this feature.
Note: While the application supports Microsoft Internet Explorer and Microsoft Edge, for best results when working with the Audio feature, we recommend using Google Chrome as your browser.
The quality of the original file has a big impact on the accuracy of the transcribed text. Factors that can work against speech-to-text accuracy include a lot of background noise or instances where multiple people are talking simultaneously.
The Audio feature supports the following audio file types: .aif, .aifc, .aiff, .au, .mp3, .oga, .snd, .wav, and .wma.
Note: The Arabic language model requires audio that is sampled at greater than or equal to 16 KHz. All other language models support audio that is sampled at 8 KHz or higher.
Note: Video files are not currently supported.

You can transcribe individual audio documents or multiple audio documents at the same time.
Note: If your current document is an unsupported audio file type or non-audio document, the features in the Audio pane are disabled, and the application displays a message.
If you select an audio document that has not yet been transcribed, the following message appears in the Audio pane: No text content to show. Transcribe audio from this file first.
If your current document is an audio document that is not yet transcribed, the Transcribe audio button is enabled on the Audio pane toolbar.
Note: If you do not see this button on the toolbar, you can pin it from the Audio pane menu to the toolbar.
Use the following procedure to transcribe an individual audio document.
1.To transcribe the current audio document, click the Transcribe audio button.
Note: Depending on the length of the audio document, it can take several minutes for the transcription to appear in the transcribed text section in the Audio pane. While the transcription is running, you can move to other documents. If you add the Audio Transcription Status field as a column in the List pane, you can track the transcription’s status (Submitted, Transcription successful, Transcription error).
2.After the audio document is transcribed, the following things happen:
oThe text transcript can be viewed in the transcribed text section of the Audio pane with time interval stamps.
oEach audio record has a .txt file that is saved in the same level folder as the native file. This text file has the same document ID as the native file.
oThe document is flagged for indexing the next time that an administrator runs an Indexing and enrichment job for the case.
Use the following procedure to transcribe multiple audio documents.
1.Return a set of supported audio documents.
2.Select the documents in the List.
3.On the Tools menu, select Transcribe audio.

The files are submitted for transcript extraction and the following things happen after the audio documents are transcribed:
oThe text transcript can be viewed in the transcribed text section of the Audio pane with time interval stamps.
oEach audio record has a .txt file that is saved in the same level folder as the native file. This text file has the same document ID as the native file.
oThe documents are flagged for indexing the next time that an administrator runs an Indexing and enrichment job for the case.
Use the Audio Transcription Status field on the Search page, shown in the following figure, to search for audio documents that have been submitted for transcription, that encountered an error during transcription, or that were transcribed successfully.
