In the current era of AI and machine learning, audio transcription is essential for creating datasets that enable computers to recognize and comprehend sound and speech. Audio transcripts provide structured data that chatbots and virtual assistant devices can use. Transcriptions can be manual or automated. Automatic transcription uses speech recognition software to create a text version of the audio file in real time, which can be faster and less expensive than manual transcription.

They make it possible to create accessible content for users with additional accessibility needs or those who would rather read than listen, and they also improve searchability and boost SEO by making keywords visible. But there are many different audio transcriptions, and each style has special uses. The type of audio you choose to transcribe can greatly impact the turnaround time and cost. For example, hard copy media like CDs and cassette tapes are typically slower to transcribe than soft copies such as digital recordings. The quality of the audio recording can also have an impact since distorted or unclear audio will be more difficult to transcribe than clear and crisp sound.

For example, a general transcript of an interview or conference call will have less need for specialized formatting than one that focuses on the pronunciation and intonation of the speech. In addition, the use of tags, markers, and punctuation can impact how long a transcript is and its accuracy. For example, ellipses indicate pauses or hesitations, and two short dashes indicate an interruption in the audio file.
