FAQs
How much does transcription cost?
Professional transcription costs $1-3 per audio minute ($60-180 per hour). Automated services (Rev AI, Otter.ai) cost $0.25-0.60 per minute. Quality, turnaround time, and accuracy affect pricing.
How long does transcription take?
Manual transcription takes 4-6 hours per audio hour for experienced typists. Automated transcription is instant but requires editing (30-60 minutes per audio hour). Complex audio takes longer.
Which speech-to-text service is most accurate?
Human transcription is 99%+ accurate. AI services: Rev.com (95-99%), Otter.ai (90-95%), Google Speech-to-Text (85-90%). Accuracy depends on audio quality, accents, and technical terms.
How can I improve transcription accuracy?
For better accuracy: use good microphone, reduce background noise, speak clearly, use proper grammar, avoid overlapping speech, provide speaker labels, define technical terms, and review/edit automated transcripts.
What audio formats do transcription services accept?
Most services accept: MP3, WAV, M4A, MP4, and AAC. Some support video files (MP4, MOV, AVI). Higher quality audio (44.1kHz, 16-bit minimum) produces better transcription results.
Do I need to transcribe my podcast?
Yes, transcripts improve SEO, accessibility for deaf/hard-of-hearing listeners, content repurposing (blogs, social posts), searchability, and reach. Many podcast hosting platforms now offer automatic transcription.
