Speech-to-text API pricing guide: Per-minute, per-hour and feature costs explained
Blog post from AssemblyAI
Speech-to-text API pricing is a complex landscape that extends beyond basic per-minute rates and involves various billing methods, feature bundles, and accuracy tiers, which can significantly impact the overall cost. Providers use different pricing models, such as bundled versus unbundled feature pricing and per-second versus per-minute billing, which can lead to unexpected expenses if not carefully evaluated. Real-time streaming transcription is generally more expensive than batch processing due to the infrastructure required for low latency, and different applications necessitate varying levels of accuracy and feature sets, affecting total costs. Providers also offer standard and premium model tiers, with premium models providing better accuracy for specialized terminology, which can be crucial for applications like medical transcription. Hidden costs, such as those related to cloud infrastructure and data privacy compliance, can further complicate cost assessments, making it essential to evaluate the total cost of ownership based on specific use cases rather than relying solely on headline rates.
