8 Killer Tips For Audio Transcription and Recording
What is Audio Transcription?
An audio transcription is simply a written record of spoken words, such as those in a video or podcast. If you’ve ever watched the closed captions on a live television event, or used your phone’s speech-to-text feature to send a message, you’ve used a simple form of audio transcription.
Depending on how it will be used, an audio transcription may include more than the words. It could also indicate pauses, music, and other sounds in the conversation or background.
Besides creating a written record of a video or audio recording, audio transcription also can help clean up and clarify what was spoken. Reading an audio transcription allows you to bypass thick accents or incorrect pronunciation. Because it records what was literally spoken, audio transcription makes things clear by removing audio distractions or a speaker’s personal ticks.
Benefits of Audio Transcription
Audio transcription has many uses for people of all ages, places, and industries. Here are just a few examples:
- Improve Accessibility: An audio transcription makes video or audio content more accessible for the deaf and hard-of-hearing. It also helps individuals in sound-sensitive environments, those with a slower Internet connection, or non-native speakers who want to translate an audio transcription to their preferred language.
- Better Comprehension: Students can use audio transcriptions of their classes to better understand the material. Lawyers can use audio transcriptions of an interview to review evidence. Doctors can create audio transcriptions of their dictations to review patient symptoms. Reading an audio transcription gives them another way to consume important information.
- Increased SEO: Audio transcriptions of video or audio content provide a source of text that search engines like Google can crawl and index for important keywords. This can help recorded content be properly indexed, giving it the chance to rank higher on search engine results.
- More Engagement: An audio transcription of a video can be used to create subtitles or captions. This can help increase video engagement and improve the rate of video completion.
- Repurposed Content: When you have an audio transcription of your content, you can easily use it to create additional content, such as social-media posts, ebook downloads, or blog posts.
Importance of High-Quality Audio Recording
Audio transcription can be valuable in many ways, but an unclear, low-quality recording can erase many of those benefits. It’s important to make sure you take steps to create the best recording possible before using it to create an audio transcription.
8 Tips and Tricks to Record Audios and Produce High-Quality Transcriptions
1. Invest in a Great Microphone and Other Recording Equipment
Whenever possible, whether you are recording a video or just audio, get an external microphone. Built-in microphones, such as those in cameras or smartphones, are not always the best quality, and it may pick up the sounds of the device itself.
Determine what type of microphone you need. For example, an omnidirectional microphone is good for recording sound from all directions, but if you have only one speaker or source of sound, choose a unidirectional mic to record from only one direction. The type of microphone you choose will also depend on the type of audio you are recording, how many speakers, and where.
If you record audio regularly in multiple locations, it’s a good idea to invest in a good portable audio recorder. This small device is handy for recording a wide variety of audio, whether it’s music, interviews, lectures, or live shows. There are many types of audio recorders available, but the Wire Realm has a list of the 10 best portable audio recorders you might consider.
“You get what you pay for” is generally true when it comes to recording equipment. Better equipment will provide better audio quality, which will give you a better audio transcription. Consider what you’re going to use it for, what your budget is, and read some reviews to find the best mic for your purpose. If you already have several microphones on hand, record some test audio with each of them to decide which one to use.
2. Reduce Background Noise
Too much background noise can complicate the audio track, potentially interfering with the audio transcription. Close windows and turn off fans, other machinery, and background music. Consider putting up “Recording in Progress” or “Do Not Disturb” signs outside the room where you will be recording.
During the audio recording, if you are close to the microphone, make sure you breathe lightly, and never directly into the microphone. If you record outside, try to shield the microphone from the wind, using either a wind protector or putting a cloth over the microphone.
3. Speak Clearly
Even with top-of-the-line recording equipment, the highest quality does not matter if you do not use it correctly. This means speaking slowly and clearly, watching your pronunciation, and avoid slurring or stuttering. Try not to speak hard consonants directly into the microphone, otherwise you could create sharp popping or hissing sounds.
If you are recording a speech, interview, or lecture, consider asking the speakers to state their name, title, and affiliation audibly. Avoid letting two people talk at once; avoid interrupting, and don’t be afraid to ask speakers to repeat themselves in case something is unclear the first time.
However awkward it may feel, don’t be afraid to allow pauses and silence. Occasional silence makes the audio transcription process easier, improving the quality of the finished transcription.
4. Center the Recording Device
If you are recording more than one speaker, try to position the audio recording device and microphone in the center of everyone who is speaking. If someone’s voice is softer or does not carry as well as others’, put the recorder a little closer to them. This will help make each speaker’s volume more even, which will improve the quality of the final audio transcription.
When using an external microphone for a single speaker, make sure it is about a hand’s width away from the speaker’s mouth. To avoid picking up bursts of air from the speaker’s mouth, try to position the microphone slightly above the speaker.
A microphone that is too close to the source can create a distorted sound. Too far from the source, however, and it can make the speaker muffled, or pick up too much ambient noise. Keeping the microphone 6-12 inches away from the speaker makes for the best recording, and makes the audio transcription easier to create.
5. Use an Audio Limiter
An audio limiter is a type of audio compressor, a device or software that helps prevent an audio recording from varying too much in volume. This is particularly helpful with preventing sound clipping and distortion if the source of the audio gets too loud.
A compressor gradually reduces a signal level above a certain threshold. A limiter, however, completely prevents the signal from exceeding a specified setting. This means that no sound beyond that setting can get through.
6. Create a Test Recording
Can’t understand the recording or a particular speaker? The transcriptionist probably can’t, either. Never underestimate the value of a test recording, especially if you are using new equipment or recording in a new or unusual location. All you have to do is make a short audio recording and play it back.
If necessary, adjust your microphone or recording device, switch equipment, or ask the person to speak up. When you’re confident with the quality, you can proceed with the full recording.
7. Never Sacrifice the Quality of Your Audio
If you’re in a hurry, low on energy, or otherwise recording under less-than-optimal conditions, it can be tempting to cut corners and hope for the best. This can create bigger issues in the long term, however.
A low-quality audio recording leads to a low-quality audio transcription. Without an accurate audio transcription, you can’t gain all the benefits you would have if you had a clear audio recording.
8. Choose the Right Transcription Service
Once you have your audio recording, you have a lot of different options for creating an audio transcription. Your first choice is to decide whether you should go with a software-based transcription service or a human-based transcription service.
Automatic transcription software can be useful if you need immediate, low-cost results. For the best accuracy and time savings, however, you’re better off using an audio transcription service provided by real human beings.
How Do You Transcribe Audio To Text?
Now that you know “What is audio transcription?” and “Why should I use audio transcription?” the next question to answer is, “How do I get an audio transcription?”
The most basic way to create an audio transcription is to go through the audio recording or video and write down the words. Without experience or the right transcription equipment, however, this option can be incredibly time-consuming and frustrating.
