What are the benefits of free iPhone/iPad transcription apps/services?

Free transcription apps and services for iPhone offer many advantages.

The biggest benefit is undoubtedly that you can significantly improve the efficiency of your transcription work without incurring any costs.

This allows you to dedicate the time previously spent on transcription to other, more productive activities.

Moreover, with the recent advancements in AI technology, even free tools can now transcribe long audio files with very high accuracy.

Another attractive feature is the emergence of user-friendly apps and services that can link with voice memos recorded on iPhone or iPad and offer extensive editing functions.

iPhone/iPad Transcription Basics: How to Transcribe Voice Memos for Free

We'll explain the key points you need to know about transcribing voice memos recorded on your iPhone or iPad into text data.

In particular, understanding the difference between the features built into iPhone's iOS and dedicated transcription apps or services is crucial.

Knowing the options for converting voice memo audio data into text will also help you choose the best tool.

What is the iOS standard feature "Voice Memos"?

The "Voice Memos" app, pre-installed on iPhone and iPad, is a convenient tool for easily recording audio.

It's used in various situations, such as recording meeting minutes, lecture notes, or capturing ideas.

Recorded audio files are typically saved in the m4a file format.

This m4a file is an Apple-specific audio format characterized by its ability to store high-quality audio in a relatively small file size.

However, the transcription capabilities of the "Voice Memos" app itself are limited, primarily to real-time input using Siri.

To efficiently transcribe recorded voice memo files, it's common to use external apps or services.

How smoothly voice memo data can be linked to a transcription tool is one of the key factors determining usability.

Why are dedicated iPhone/iPad transcription apps/services necessary?

While iPhone and iPad iOS have voice input functionality via Siri, this is primarily suitable for transcribing short, real-time utterances.

For transcribing long, pre-recorded voice memo files later, or when higher accuracy and editing features are required, dedicated transcription apps or services are necessary.

Dedicated tools have highly tuned speech recognition AI engines, capable of accurately converting audio to text even in noisy environments or with multiple speakers.

They often include convenient features that support transcription work, such as automatic punctuation insertion, speaker separation, and timestamping.

With an increasing number of high-performance transcription apps and services available for free, utilizing these can significantly save time and improve accuracy compared to manual transcription.

To make the most of your valuable audio data recorded with iPhone or iPad voice memos, the existence of dedicated AI transcription tools is essential!

Types of iOS-compatible transcription apps/services: Installable and Browser-based

Transcription tools available for iPhone and iPad iOS are broadly categorized into two types: “installable apps” and “browser-based services.”

Installable apps are downloaded directly to your iPhone or iPad from the App Store and used.

The advantages include that once installed, they can sometimes be used offline (though the transcription process itself often requires an internet connection) and can integrate closely with iPhone/iPad features.

On the other hand, disadvantages include the effort of app installation and updates, and the consumption of storage space on your iPhone or iPad.

Browser-based services are accessed through web browsers like Safari.

A prime example is "Mojiokoshi-san".

The advantage of this type is that no app installation is required, so it doesn't burden your iPhone or iPad's storage and isn't affected by iOS version updates.

If you create an account, the convenience of being able to access it from any device is also a notable feature.
