How to Choose a Transcription Company: A Complete Guide
June 8, 2025


For those of you with such concerns, we will introduce how to choose a transcription service (or audio to text service) and the best methods for transcription.
Transcribing audio from meetings or interviews into text can be very time-consuming if you do it yourself by typing. Therefore, paying a specialized company (transcription service provider) to outsource the work is one option.
Additionally, besides companies that use professional transcribers, we also recommend utilizing AI transcription services.
We will thoroughly explain the best ways to efficiently transcribe audio (or convert audio to text) using services provided by various companies!
How to Hire a Professional Transcription Company (Transcription Service Provider)?
How should you go about hiring a professional company for transcription (audio to text services)?
First, we'll explain the types of transcription service providers and how to choose the best one.
What is Transcription (Audio to Text)?
Transcription (also known as audio to text or tape transcription) is the process of converting recorded audio into written text.
- Meeting minutes
- Interviews
- YouTube videos and other media
By converting such content into text, it can be preserved as a record, used for magazine or blog articles, and utilized more conveniently.
Transcription has been a profession since the era of cassette tapes for recording, which is why it is still sometimes referred to as "tape transcription."
There are two main methods for transcription:
- Typing out text while listening to audio
- Automatic conversion using speech recognition AI
What are Transcription Companies (Transcription Service Providers)?
Since typing out transcriptions while listening to audio is time-consuming and labor-intensive, many companies offer transcription (audio to text) as a service.
By relying on a specialized company (transcription service provider), you can streamline the transcription process and convert audio to text quickly and smoothly.
Transcription Companies Use Professional Transcribers
Transcription companies employ professional transcribers who type out text while listening to audio.
Because experienced transcribers handle the work, they can accurately deal with difficult points such as:
- Technical terms
- Homophones
- Speaker's slips of the tongue
Hiring a Transcription Company Costs Money and Time
However, naturally, using a transcription service provider incurs costs.
Since you are hiring a professional, the cost is a bit higher compared to "AI transcription," the other method of transcription.
Of course, transcription only begins after you provide the audio data, so you will also need to wait a few days for delivery.
*Some transcription service providers offer expedited services (e.g., next-day or same-day delivery), but these come at a much higher price.

This transcription service is recommended when you need to write academic papers in a foreign language.
AI Transcription is Also Highly Recommended
So far, we've introduced companies where human transcribers (typists) perform transcription. However, if you're outsourcing transcription, "AI transcription" is also highly recommended.
AI transcription is a service where an AI speech recognition engine automatically transcribes audio files once you upload them.
In recent years, with the rapid advancement of AI, the performance of AI transcription has significantly improved, making it possible to achieve very high accuracy comparable to professional transcription services.
Speech recognition is a field where AI particularly excels, so it's possible to get transcription quality on par with what you'd receive from a dedicated transcription company.
Moreover, AI offers unique advantages.
Transcription Completed in a Short Time
When you request services from the companies introduced in this article, standard delivery times are at least one business day, even for short recordings.
Furthermore, longer audio recordings require even longer delivery times.
While many companies offer same-day service for an express fee, the additional cost can be quite high.
In contrast, AI transcription services can complete transcription in a very short amount of time.
Amazingly, short audio files can be transcribed in just a few minutes, and even long files are completed in about 10 minutes!
Transcription Available Anytime, Instantly
When using a company with human transcribers, you naturally need to place your request during business hours.
If you need transcription after business hours, you'll have to wait until the next business day.
Some companies may not operate on Saturdays, Sundays, or public holidays.
On the other hand, AI transcription services, unlike traditional transcription companies, are available 24 hours a day, 365 days a year.
Interviews sometimes take place at night to accommodate the other party, but even then, you can transcribe immediately after completion.
Foreign Language Transcription Available at the Same Price
AI transcription services are also highly recommended for foreign language transcription!
Transcribing foreign languages, including English, requires different skills than transcribing Japanese, so transcription companies often charge higher rates for foreign languages.
Also, since there are fewer transcribers with foreign language skills, the options for companies that can handle foreign language transcription are limited.
This is where AI transcription services come in handy.
With AI transcription services, foreign language audio can be transcribed just like Japanese.
What's more, unlike companies with human transcribers, you don't need to pay any additional fees.
A point to note is that when using AI for foreign language transcription, you should check in advance if the service supports the language you want to transcribe.
It's recommended to choose a service that can transcribe many languages, like "Mojiokoshi-san," which supports 100 languages.
Affordable Pricing
Finally, AI transcription services can transcribe at a lower cost than human transcription companies.
Companies that rely on human transcribers incur labor costs for their expert staff, which leads to higher prices.
In contrast, AI transcription services do not require labor costs because computers handle the processing.
While AI transcription services often operate on a monthly subscription model, it's common for the monthly fee to be lower than the cost of transcribing a single audio file by a human transcriber at a traditional transcription company.
Recommended AI Transcription Service: "Mojiokoshi-san"
For those looking for an AI transcription service, "Mojiokoshi-san" comes highly recommended.
"Mojiokoshi-san" is an AI transcription service that utilizes the latest high-performance AI.

Why Not Try Transcribing with a Convenient Service?

Furthermore, AI transcription services utilizing speech recognition AI have rapidly developed in recent years.
