How To Convert Audio File To Text
AUDIO FILE TO TEXT BENEFITS AND OPTIONS!
There is growing interest to find reliable ways to convert an audio file to text. There are many reasons for this research ranging from individual use to commercial applications. In this brief guide of “how to convert audio file to text” we list a couple of key benefits to convert an audio file to text and also review some of the best options to do this.
WHY CONVERT AUDIO FILE TO TEXT?
What are some common reasons why people convert audio file to text?
The process to convert audio file to text is important in many situations. Examples of users who have their audio files converted include researchers, presenters, doctors, and lawyers. These users mostly require a transcript of their audio to assist them with keeping a record of statements made, decisions committed to or to review key findings.
As a transcription company, we hear lots of requests for this service. Four frequent reasons clients ask us to convert their audio file to text include a need to share information from the audio with others, a requirement to keep text records of what was said, to help participants in an audio recording to focus on the conversation taking place and reflect on the discussion later, and to have a method to quickly track or find information in an audio recording.
We briefly take a look at each of these benefits.
First of all, it’s often a great way to share information. People enjoy listening to audio. Think of podcasts, audio books, voice notes or even listening to videos or webinars. But accessing such files can be difficult at times as people can be hindered by not always having the right technology at hand or be in a position to listen or watch. So, converting an audio file to text would allow anyone to read what was said in the audio recording, at any time.
Suppose you’re holding a meeting or a conference, but some people aren’t able to attend. That means that they will miss out on all the content of the discussion unless they manage to get hold of the notes. Again, this is a great example where converting an audio file to text of the discussion ensures that anyone not present will not miss out on any information.
LISTEN TO THE CONVERSATION
Often staff or attendees at your meeting can spend time scribbling notes, trying to take down as much information as possible. In such cases, they often miss important points. If instead, you record the meeting discussion and get your audio file to text transcribed, you can furnish everyone with a record of the information and decisions made. At the same time this step ensures everyone can pay full attention to the conversation and not lose train of thought or miss any key points.
FIND RELEVANT INFORMATION
When writing a dissertation or doing research, for example, it might get quite difficult to track the information down from an audio file, especially if you have to listen to hours and hours of recordings to find a pertinent comment. With lots of audio recordings getting your audio file transcribed will help you search the document for required keywords. You can then also and copy and paste selections from the transcript right into another document.
HOW TO CONVERT AUDIO FILE TO TEXT?
So, what are the options available to convert an audio file to text?
There are 3 options you can consider to achieve this. We list each option with our thoughts and a quick “pro and con” to perhaps help you evaluate which method you want might like to choose.
OPTION 1: USE TRANSCRIPTION SOFTWARE
This is your do-it-yourself option.
In this case, you need your own computer/ mobile/ technical listening equipment and possibly additional equipment such as foot pedals to hear the audio and type out the transcript. The software must be capable of playing back/ repeating audio comments as you will have to listen over (and sometimes multiple times) audio speech which might not be clear (due to background noise, over speaking, faintness, etc). There are some good choices out there, depending on what you need and are willing to spend.
Our transcription software recommendations include:
- Express Scribe (all-around performer and very popular),
- Start-Stop Universal Transcription System (fairly good, some mixed reviews),
- Inqscribe (another well-known brand), and
- Dragon Naturally Speaking (the most popular solution, especially for dictation/ single speakers).
QUICK PRO AND CON
- Key benefit: Not expensive, minimal cost or even free options exist (great if you have no money).
- Key challenge: You need lots of time!
OPTION 2: MACHINE TRANSCRIPTION
Another do-it-yourself but assisted solution.
Ahhhh, the elixir of new technology, artificial intelligence (or AI to you techies) and all things virtual. So does machine transcription really work?
Well, yes and no.
There are some machine transcription solutions such as speechmatics that offer “audio file to text converters” in a range of languages, as well as a few machine transcription technologies that also prompt dialect choices (such as US English, British English, Australian English). Then there are other machine transcription providers, such as Trint, that push software which will “machine transcribe” your audio while you edit alongside – essentially letting the machine convert audio file to text, while you correct the text.
Software developers have been working on machine transcription software that will convert audio files to text for many years. With thousands of accents and dialects spoken worldwide, nearly uncountable number of differences in the way people speak – speed of speech, enunciation, pronunciation, slurring of speech, swallowing of vowels, the accuracy level of transcription software is still lower than the ability of a trained and experienced human transcriber ear.
Add to that an excellent command of language, sharp hearing, and knowledge of the various subject matter and the relevant terminologies, which makes the context of any conversation also important, machine transcription solutions are still working at levels that can be largely disappointing as a single solution for general users if an accurate transcript is required.
The accuracy of human transcribers is estimated to be around 95% depending on large variances in quality of recording audio (see our recording guidelines for quality sound). The human ear is designed to hear a lot of detail, especially in group conversations, noisy backgrounds and a lot of other challenging acoustic situations. Machines, however, are still mostly trained for the single speaker (dictation). Machine solutions tested by our company using general audio within the language and dialect offered by the converter still remained significantly lower in accuracy than the human ear – around 70% down to nothing (depending on the quality of audio we are talking about – excuse the pun!)
QUICK PRO AND CON
- Key benefit: Bulk transcription quickly at relatively low cost.
- Key challenge: You need lots of time to go over mistakes and correct!
OPTION 3: AUDIO TRANSCRIPTION SERVICES
A do-it-for-you option.
This option still remains a preferred choice for many individuals, companies, and institutions, especially where accuracy and speed are important considerations. The key value of this service option is to get a highly accurate text version of what was said in the time you require.
Users of this option also come from many sectors that require a range of academic transcription, medical transcription, legal transcription, financial transcription, research transcription and even media transcription solutions. There are many more subject areas of course, but essentially, services in this sector must also be capable of offering subject expertise to ensure the audio file is correctly transcribed. Missing some key terms can sometimes even make the difference between a decision to operate on someone to making a poorly informed decision on strategy!
Ironically, choosing the best service remains difficult. If you google (or bing!) the internet these days you will see many transcription companies with promises of 99% accuracy in the transcript! There are even one or two services that promise 200%(!) accuracy (how is that even mathematically possible?). Anyhow, the bottom line is that selecting the best transcription service is still often a bit of a gamble at times.
Key ways to help narrow down your transcription service of choice would be to seek other user references, check the company reputation and (often most overlooked but relevant) establish how long they have been in the market. Many transcription services with a poor record tend to have short lives!
So entrusting the right service with your important audio recording is vital. Cheap pricing and over-promising expectation frequently end in disappointment – yours. Usually, this leads to even more costs or eventually having no choice but having to convert audio file to text yourself. We know as we have seen this with clients coming to us from other transcription services for this very reason.

- Key benefit: You save time
- Key challenge: You spend money
