Can ChatGPT Transcribe Audio
Saving time and effort with Notta, starting from today!
ChatGPT can transcribe audio to text using OpenAI’s Whisper API. ChatGPT helped launch the global AI market that's now worth over $136 billion, and its audio transcription features are getting better every day.
You no longer need a stenographer or typist to transcribe a recording. AI lets you automatically convert any video or audio to text in minutes.
ChatGPT's speech-to-text Whisper API is a popular tool that is making headlines with its ability to automate audio transcription.
This article explains how the Whisper API works and how you can use it to transcribe audio. It also highlights some common uses of the Whisper API, like transcribing meetings, interviews, and medical visits.
Let's get started!
Can ChatGPT transcribe audio?
Yes, ChatGPT can transcribe audio and video files into text in over 50 languages. It can also translate many more languages into English. ChatGPT does this using a speech-to-text feature powered by OpenAI's Whisper API.
When you upload an audio file, the AI tool uses a speech recognition algorithm to make sense of the audio and generate a transcript.
Introducing the ChatGPT speech-to-text feature
ChatGPT voice-to-text is a feature of the Whisper API, an automatic speech recognition system by OpenAI trained on more than 680,000 hours of audio in different languages.
So, how does Whisper's speech recognition actually work?
When you upload audio to the API, the data is divided into 30-second parts. Whisper converts each part into an image known as a spectrogram, which visually describes all the audio frequencies in that part. Next, the images go through an encoder to convert them into tokens that Whisper can process. Finally, the data is passed to a decoder, which converts the tokens into readable text.
Language support
The Whisper audio-to-text model provides two endpoints that assist with audio transcription into the original language and translation into English. Both endpoints support numerous languages, including English, Arabic, French, Japanese, Chinese, German, and Spanish. The standard word error rate in these languages is less than 50%, which is an industry standard benchmark.
It is worth noting that OpenAI has trained the language model in 98 different languages so far.
File support
The API can transcribe audio files in multiple formats, including MP3, WAV, MPEG, MP4, M4A, MPGA, and WebM. However, there is a default audio size limit of 25 MB. If the audio file is larger, you can compress it using an online tool or divide it into smaller chunks before uploading.
Capability on PC, Laptop, and iOS:
ChatGPT's speech-to-text feature is accessible on PCs, laptops, and iOS devices.
You should use OpenAI Python v0.27.0 on your PC and laptop to make sure the code runs smoothly. You also need to provide the audio in the specified format. For those using an iOS device, you may need to download the official ChatGPT app for your iPhone to access the service.
Prompting
Like any other AI model, a good prompt will improve the quality of your audio transcript.
The Whisper audio-to-text model can adjust its formatting based on your prompt. For example, if you say “use all caps” and “use the Oxford comma,” you'll get a transcript in all caps with Oxford commas in the right places.
You can also use the prompt to correct words and acronyms that Whisper misidentifies in the audio.
However, there are limits to what you can do with Whisper AI prompts. Compared to other models, they give you less control over style and tone, and more control over basic formatting.
Even with careful prompting, complex audio can lead to mistakes, but Whisper is still one of the best ways to transcribe audio content quickly and accurately.
Applications of ChatGPT speech to text
You can use an AI transcription service like Whisper API in several ways, but these are the most common.
Content creation - It can help content creators repurpose their content.
Healthcare - Doctors can use it to transcribe their patient notes
Finance - It can help in transcribing financial reports and vital calls
Education - Can help in transcribing lectures and discussions.
Marketers - It can help in transcribing meetings.
Beyond transcription, there are many other ways to use ChatGPT, such as content creation, market research, and customer service. Thanks to its impressive natural language processing (NLP) capabilities, it is a very flexible platform.
Start transcribing with AI
ChatGPT's voice-to-text feature will help you transcribe audio in over 50 languages and translate many others into English. However, depending on the audio quality, language choice, diction, pronunciation, and background noise, it may not be perfectly accurate.
ChatGPT's Whisper API works on multiple devices, but it's not a good choice for beginners. Notta is a user-friendly speech-to-text platform that helps you transcribe audio content with up to98% accuracy. It's available on the web, mobile devices, and as a Chrome extension, so you can easily access it anytime you need a transcript.
