What Makes a Good AI Transcription Service?
Choosing to utilize an AI transcription service over human transcription depends on your needs and constraints such as deadlines and budgets. For example, if the accuracy of your transcription is the top priority, and time and money aren’t an issue – human transcription is the way to go.
The goal of every AI speech-to-text engine is the same – to recognize when a word is spoken, what the word is, and what the word isn’t. However, every AI is trained on different word sets and audio types, making the programming of each one slightly different. Most AI models are also backed by Automated Speech Recognition (ASR), which brings the benefit of speaker identification. This prevents the AI from “gluing together” sentences or snippets from different speakers.
The larger accuracy hurdle that AI transcription services must overcome is complex audio – files with background noise, heavy accents, and people talking over each other pose a much bigger challenge for AI models than human transcriptionists.
All of this being said, Rev’s generative AI has still outperformed other leading AI transcription models – when tested on 30 podcast recordings, Rev still achieved accuracy rates as high as 86%. Rev also recently beat out Google, Amazon, and Microsoft for ASR accuracy rates in internal tests.
If your specific needs put speed of delivery above transcript accuracy, AI transcription services are a no brainer – Rev’s generative AI can deliver transcripts in minutes, not hours or days.
Simply upload your file to Rev’s AI Transcription Services checkout page, and receive your video or audio transcript within minutes. We’ll also send you an ETA once your uploaded file is received and processed.

When You Might Prefer to Use Human Transcription
AI transcription services work best with as few speakers as possible and limited background noise. It is ideal for transcribing notes you’ve dictated for yourself or podcasts with limited overlapping speech.
Human transcription is preferable if the audio is complex with mixed accents, background noises, or lots of speakers. It is also preferable if accuracy is paramount, for example, for legal reasons or high-quality, customer-facing text. Law firms, market researchers, education providers, and video companies often favor human transcription.
Luckily for you, you don’t have to go far to find the best traditional transcription services, either. Rev’s top human transcription service guarantees a 99% accurate transcript. That means a maximum of 10 errors per 1,000 words. Plus, it’s fast and competitively priced.
