What is automated transcription?
Automated transcription is the process of converting speech from audio or video files into written text using AI and machine learning. Unlike manual transcription by humans, automated transcription uses advanced speech recognition algorithms to process audio in minutes rather than hours, delivering accurate text at a fraction of the cost. Sonix's automated transcription works with any audio or video format and supports 54+ languages.
How accurate is automated transcription?
Sonix delivers up to 99% transcription accuracy for clear audio recordings. Our AI is trained on millions of hours of audio across different accents, industries, and recording conditions. Accuracy depends on audio quality, background noise, and speaker clarity. For specialized terminology like medical or legal terms, Sonix's Custom Dictionary feature lets you add industry-specific words to further improve accuracy.
How long does automated transcription take?
Sonix transcribes audio and video files in approximately 5 minutes per hour of content. A 30-minute meeting recording is typically transcribed in under 3 minutes. This is significantly faster than manual transcription, which typically takes 4-6 hours per hour of audio. Processing time may vary based on file size and server load, but most transcriptions complete within minutes.
How much does automated transcription cost?
Sonix charges $10 per hour of audio transcribed with pay-as-you-go pricing. There are no monthly fees or subscriptions required. New users get 30 minutes of free transcription to try the service. This is significantly more affordable than professional human transcription services, which typically charge $100 or more per audio hour. Enterprise plans with volume discounts are available for high-volume users.
