Pre-Recorded Audio Transcription
The DeepgramClient
has a Transcription.Prerecorded
property that allows you to request transcripts for pre-recorded audio. To request a transcript for a pre-recorded particular audio file, you'll use the Transcription.Prerecorded.GetTranscriptionAsync
method.
Transcription Sources
There are two types of sources that can be provided for transcription:
UrlSource
Provides a url to the file to transcribe.
var response = await deepgram.Transcription.Prerecorded.GetTranscriptionAsync(
new UrlSource("URL_TO_FILE"));
StreamSource
Provide a stream containing the file to transcribe.
using (FileStream stream = File.OpenRead("PATH_TO_FILE"))
{
var response = await deepgram.Transcription.Prerecorded.GetTranscriptionAsync(
new StreamSource(stream, "MIMETYPE_OF_FILE "));
}
Helper Functions
The SDK provides a few helper functions for converting pre-recorded transcriptions into common caption formats, like WebVTT and SRT.
Utterances are Required for Helper Functions
In order to use the helper functions, the
Utterances
feature must be used when transcribing the audio.
Converting to WebVTT
Each pre-recorded transcription object provides a ToWebVTT
function to convert the transcript to the WebVTT format.
var response = await deepgram.Transcription.Prerecorded.GetTranscriptionAsync(
new UrlSource("URL_TO_FILE"),
new PrerecordedTranscriptionOptions()
{
Punctuate = true,
Utterances = true
});
var srtTranscript = response.toWebVTT();
Converting to SRT
Each pre-recorded transcription object provides a ToSRT
function to convert the transcript to the SRT format.
var response = await deepgram.Transcription.Prerecorded.GetTranscriptionAsync(
new UrlSource("URL_TO_FILE"),
new PrerecordedTranscriptionOptions()
{
Punctuate = true,
Utterances = true
});
var srtTranscript = response.ToSRT();
