Transcription accuracy vs. transcription quality: why the gap matters
AssemblyAI argues that the advertised per-hour cost of speech-to-text APIs is misleading, as hidden expenses like human correction labor and downstream failures can multiply the actual cost. The company emphasizes that accuracy, not just the base rate, is crucial for total cost of ownership, especially in production deployments. Furthermore, AssemblyAI highlights that traditional accuracy metrics like Word Error Rate (WER) fail to capture crucial aspects of perceived transcript quality, such as speaker mislabeling and the impact of audio tags, which can erode user trust and product reliability.
