Why Convert Audio to Text?
In Which Cases Is It Necessary?
- Studying and Lectures: it’s simpler to make notes from recordings if you already have text at hand.
- Interviews and Podcasts: automatic transcription helps you quickly find quotes and specific segments.
- Creating Subtitles Online: a text version broadens your reach, making content more accessible to people with hearing impairments.
Who Most Often Uses Such Services?
- Journalists: for rapid transcription of interviews.
- Students and Researchers: to avoid wasting time manually typing out recordings.
- Business and Marketers: for meeting protocols, content repurposing, and smoother document flow.
How Does Automatic Speech-to-Text Conversion Work?
Principles of Neural Networks and Algorithms
Most websites utilize automatic speech recognition via deep learning. The algorithms analyze acoustic features and link them to words from a database. The outcome is a ready-made text transcription.
Limitations and Recognition Accuracy
- Noisy Environments or musical background reduce quality.
- Not all engines equally well interpret dialects and specialized terms.
- Some services demand a clear recording for high accuracy.
Top Online Services for Converting Audio to Text
Below are popular platforms where you can transcribe audio to text online for free or for a reasonable fee.
Google Docs
What it is: Google provides a speech recognition tool, but generally for specialized tasks. However, there’s also a free method through Google Docs’ built-in voice input.
Pros: Completely free for voice-to-text online using the integrated voice typing function. Supports various languages.
Cons: Limited functionality; if you need to convert audio to text online from a file, you’ll have to add external plugins or use workarounds.
Cost: 0 rubles, requires a Google account.
Speech To Text
Key idea: A relatively new project, updates occur frequently. Closely tied to a Telegram bot, which can either simplify or complicate the workflow.
Pros: Uses machine learning, able to convert sound to text online with a paid model in limited volumes, offering flexible settings.
Cons: Russian language only; for stable functionality you need a paid plan, daily upload limits exist.
Cost: Based on duration, some features are free (trial).
Speechlogger
What it is: A popular service with numerous settings and a user-friendly interface.
Pros: Supports MP3, WAV, OGG; real-time speech transcription is possible. Includes a subtitles feature and “live” dictaphone function.
Cons: No complete free version, but it does have a demo; primarily focuses on English, though other languages are also available.

How to Choose the Best Service for Transcribing Audio?
Free vs. Paid Solutions
If you need a one-off online audio-to-text conversion, free limits will suffice. For regular or large-scale usage, especially if you want higher accuracy, it’s logical to pay for a plan.
Which Languages Do the Services Support?
When choosing a platform, check the list of languages and accents. If you plan converting voice to text online in multiple languages, you’ll need a service with global support (like Transkriptor or Speechtotext).
Which Files Can Be Uploaded and Transcribed?
Most services handle MP3, WAV, AAC, OGG, etc. Some can only capture audio directly from a microphone, while others impose a maximum file size: if you want to process large audio volumes, file-size limits might get in the way.
GPT as a Substitute for Transcription Services
In recent months, GPT models have grown advanced enough to handle audio files and recognize speech in virtually any language. Although GPT was originally intended mostly for text, developers have added modules that can analyze an audio stream, extract linguistic data, and convert voice to text with remarkable accuracy.
Many current projects leverage GPT’s capabilities for text and audio processing. Traditional online services for transcribing audio to text, discussed above, are gradually giving way to neural networks like GPT, which can not only transcribe speech but also simultaneously translate it into different languages—all in one comprehensive solution.
