How do I transcribe an audio message to a text?

Audio transcription is the process of converting speech from an audio recording into written text. It involves listening to audio files and manually typing out the words into a transcript document. Accurate transcripts can serve many useful purposes across different industries.

According to Simonsaysai, transcriptions, captions, and subtitles increase accessibility for users. People who are hearing impaired or on the go can still get the key information from audio and video content through text alternatives. Transcripts also make audio and video content more findable and usable online since text is search-friendly.

As Transcriptionhub notes, audio transcription helps several industries like legal, academic research, and media. It allows important audio content like interviews, focus groups, lectures, and conferences to be studied, searched, shared and reused in various applications.

Transcription Methods

There are a few main transcription methods people use to transcribe audio to text:

Manual Transcription

Manual transcription involves a person listening to an audio recording and manually typing out the words into a document. This produces highly accurate transcripts, as human transcribers can understand nuances and context. However, manual transcription is time-consuming and expensive, especially for long recordings. It works best for short audio or when high accuracy is critical.

Automated Services

Automated transcription services utilize speech-to-text technology to automatically convert audio to text. Services like Trint, Temi, and Rev allow users to upload audio files which are transcribed by AI. These services are more affordable, faster, and can handle large volumes of audio. However, they may not be as accurate as human transcription. Automated services are best for quick, rough transcriptions.

Speech-to-Text Software

Speech-to-text software like Dragon NaturallySpeaking allows transcribing audio in real-time as it’s played. The user can listen to the recording through a headset while dictating the words into the program. This achieves higher accuracy than fully automated services. However, there is still a time investment involved. Speech-to-text works well for frequently transcribing moderate amounts of audio.

Manual Transcription

Manual transcription involves listening to an audio recording and typing out the speech word-for-word into a text document. Here is the step-by-step process for manual transcription:

  1. Get a good set of headphones to clearly hear the audio.
  2. Use a foot pedal or keyboard shortcuts to control playback.
  3. Listen to short sections of the recording, pausing and rewinding as needed.
  4. Type what you hear into your document, being careful not to miss any words.
  5. Use punctuation to indicate pauses, inflection, and sentence structure.
  6. Proofread the transcript while listening to verify accuracy.
  7. Double check spellings of proper names or unfamiliar words.

Here are some tips for maximizing accuracy when doing manual transcription:

  • Work in a quiet environment without distractions.
  • Use high-quality audio recordings with clear sound.
  • Take breaks to avoid fatigue.
  • Look up transcripts or scripts if available.
  • Have a second person proofread the transcript.
  • Mark unintelligible portions to review later.

Doing manual transcription well takes patience, practice, and careful listening. Following these steps can result in highly accurate transcribed documents.

Automated Services

Many companies now offer automated transcription services that use speech-to-text technology and advanced algorithms to automatically convert audio to text. Popular services include Trint,, Sonix, and Temi.

These services offer a fast and relatively affordable way to transcribe audio files. Pricing starts around $0.10 to $0.50 per minute of audio. Features often include searchable transcripts, speaker separation, time-stamping, and the ability to edit and share transcripts.

The main downside is that accuracy rates are typically 80-90%, compared to 95-99% for human transcription. Accuracy varies based on audio quality, background noise, number of speakers, accents, and technical terms. However, services are continually improving their algorithms and some allow human editing to correct mistakes.

Overall, automated services provide a great option for quickly transcribing audio when perfect accuracy is not required. They can save significant time and money compared to manual transcription.

Speech-to-Text Software

Speech-to-text software allows you to dictate speech which is transcribed into text. There are built-in options like Windows Speech Recognition as well as third-party options like Dragon that offer robust transcription capabilities.

Windows 10 includes a built-in speech recognition feature called Windows Speech Recognition that can transcribe spoken words into text. To use it, go to Start > Settings > Time & Language > Speech and turn on the Dictation feature. You can then press Win + H to start dictating. Windows Speech Recognition has the benefit of being free and integrated into Windows, but it has limited functionality compared to paid third-party options.

Dragon is a popular speech recognition software by Nuance Communications. Dragon has powerful voice command capabilities and deep learning technology to accurately transcribe speech. It allows real-time transcription by speaking into a headset microphone. Dragon also has productivity features like auto-formatting text and controlling applications by voice. However, it costs money to purchase unlike the free built-in Windows option.

A key component of accuracy for speech-to-text software is properly training it to recognize your voice. Both the Windows and Dragon options require you to read text prompts aloud to calibrate the software. The more training done, the better it will understand your particular voice characteristics and transcription needs.

Improving Accuracy

Accuracy is crucial for any audio transcription. There are several techniques that can improve accuracy across transcription methods:

For manual transcription, take time to repeatedly listen and carefully review the transcript for any missed words or errors. Use headphones to clearly hear the audio. Pause frequently to ensure every word is captured. Reviewing the transcript while listening further improves accuracy.

For automated services, utilize features like customizable vocabularies and language models. AWS Transcribe allows users to create custom vocabularies with unique terminology to improve accuracy for specialized content. Genesys also provides recommendations to optimize audio quality and speech characteristics to improve automated transcription.

For speech-to-text software, train the software to recognize your voice and adapt to your speech patterns over time. You can also manually correct the transcript by editing errors to further improve accuracy.

Regardless of transcription method, carefully editing the final transcript is key. Listen again while reading the transcript and correct any remaining errors. Have a second person proofread as well. This helps finalize an accurate transcript.

Transcribing Audio Formats

Audio files come in many different formats like mp3, wav, wma, m4a, and more. The most common formats are mp3 for music and podcasts, and wav for uncompressed audio. Most transcription services and apps can handle transcribing common formats like mp3 and wav. However, some may have issues with less mainstream formats like wma or m4a. In that case, you may need to convert the files first before transcribing.

There are many free audio converter tools available to convert between formats. Audacity is a popular open-source audio editor that can also convert between formats. Online converters like Convertio allow you to upload audio files and download them converted to another format. For large batch conversions, Freemake Audio Converter is a good option. The key is finding a tool that supports converting the specific format you need to transcribe into a more compatible format.

Once you’ve converted the audio files into a supported format like mp3 or wav, you can then feed them into your transcription service or app of choice to get an accurate text transcript.

Specialized Transcription

Certain industries require specialized transcription services to accurately capture industry-specific terminology and formatting. Some common areas requiring specialized transcription include:

Medical transcription involves transcribing doctor’s notes, prescriptions, patient records, and other health-related audio into text documents. Accuracy is critical to avoid legal issues or harming patients. Medical transcriptionists must be familiar with medical terminology and shorthand techniques doctors use.

Legal transcription involves transcribing legal proceedings, attorney dictations, depositions, client meetings, and more into properly formatted legal documents. Legal transcriptionists must know legal terminology and how to properly format court documents.

Transcribing sensitive content like medical records or court proceedings requires upholding privacy laws and confidentiality agreements. Proper information security measures must be in place to protect sensitive data.

Alternatives to Transcription

While full transcription translates all the speech from an audio file into text, there are alternative techniques that summarize or extract key details:

  • Speech summarization – Software identifies the main topics discussed in the audio and summarizes the key points. Highlights the most important elements but does not transcribe the full speech word-for-word.
  • Keyphrase extraction – Technology automatically extracts the most important phrases and keywords from speech. Can highlight the core concepts without needing to transcribe the full content.

These alternatives provide concise overviews of recordings without the time needed for complete transcripts. They are useful when full transcripts are not required, or for skimming audio/video to understand main themes before committing to a full word-for-word transcription.

As per the provided guidelines, I have limited urls to only 1 cited source and focused on the requested topics of speech summarization and keyphrase extraction. Please let me know if you would like me to modify or expand this section further.


Transcribing audio recordings is time consuming, but it allows for easy referencing, searching, sharing and deeper analysis of information. By first assessing the clearity of the audio, considering the content, format, length, and speaker information, you can determine if manual or automated transcription services are best suited to your needs.

Manual transcription, while labor intensive, allows for the highest accuracy when transcribing audio, correcting errors and formatting documents. Speech-to-text software and services provide a faster alternative, but can struggle with accents, technical vocabulary and background noise. Regardless of method, reviewing transcripts and correcting errors is important for high quality results.

In closing, assess your transcription needs, budget, and target accuracy to determine if manual or automated services will provide the right solution. Both methods have the ability to convert important audio into easier to access and searchable text documents.
