Transcription Service: Converting Speech to Text Efficiently

What is a Transcription Service?

A transcription service is a professional service that converts spoken words from audio or video recordings into written text. These services can be manual, where human transcribers do the work, or automated, using advanced speech recognition software. Transcription services are widely used in various fields, including legal, medical, academic, and business sectors, to create accurate text records of spoken content.

How Does a Transcription Service Work?

Transcription services operate by processing audio or video recordings and converting the spoken content into text. Here’s a simplified overview of the process:


The audio or video content is recorded using devices such as smartphones, digital recorders, or conferencing systems.


The recording is uploaded to the transcription service platform, which may use human transcribers, automated software, or a combination of both to process the audio.


The service listens to the audio and transcribes it into text. Manual transcription involves a person typing out the content, while automated transcription relies on software to recognize and transcribe the speech.

FAQ - Frequently Asked Questions

What is transcription process?
Each audio file is tested, transcoded, and then transcribed using the Whisper model from the OpenAI API.
How long does it take to get a transcript?
The processing time for your transcript will depend on the length of the audio file. Typically, shorter voice messages can be transcribed quickly using OpenAI speech-to-text API.
What are the maximum file size for transcription?
Note that our transcription service has a file size limit of 20 MB.
What is the maximum duration you can transcribe?

We currently have a file size limit of 20MB. Given that most voice messages are encoded with a constant bitrate and a single channel (mono, no stereo), we can calculate the maximum duration of a file using the following equation:

Duration ( seconds ) = File Size ( bits ) Bitrate ( bits/second )

Applying this equation to our 20MB limit and a bitrate of 64 kbps (commonly used by the iPhone recorder app), we arrive at a maximum duration of approximately 43 minutes and 41 seconds. To easily calculate durations for different file sizes and bitrates, you can use our audio duration calculator.

Do I need to transform the audio before sending it to my email address?
No, this is not necessary. will automatically transcode your audio file upon receipt into the format expected by the OpenAI API.
