@GrandhisilaJVSNagalakshmi-2180 Thanks for the question. The audio files can have a length of several hours. We recommend to use batch transcription v3.0 that can point to audio files using a typical URI or a shared access signature (SAS) URI and asynchronously receive transcription results. With the v3.0 API, you can transcribe one or more audio files, or process a whole storage container.
Samples are available in our github sample repository (C# and python https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/batch).
