FAQ - Frequently Asked Questions

What is audio2text.email 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 10 MB.
What is the maximum duration you can transcribe?

We currently have a file size limit of 10 MB. 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 10 MB limit and a bitrate of 64 kbps (commonly used by the iPhone recorder app), we arrive at a maximum duration of approximately 21 minutes and 51 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 audio2textemail.com email address?
No, this is not necessary. audio2text.email will automatically transcode your audio file upon receipt into the format expected by the OpenAI API.

Since email is an established communication method, it's likely to persist, offering longevity.
What do the terms audio2text, voice2text, and speech2text mean?
The terms audio2text, voice2text, and speech2text all refer to the same concept: converting spoken language or audio content into written text. These terms are essentially interchangeable. The "2" in these terms is a common convention in tech and online services, serving as a shorthand for "to" or "into". So "audio2text" can be read as "audio to text" or "audio into text". This convention is often used to create concise, easy-to-remember domain names. In our case, audio2text.email, voice2text.email, and speech2text.email all lead to the same transcription service, just using slightly different terminology to describe the process of converting audio into text over email.
