MarkTechPost发布了语音代理API延迟基准，帮你找到最适合低延迟场景的推理服务。
该基准测试评估了语音堆栈各层的延迟表现，包括LLM、语音转文本、文本转语音和语音转语音。测试数据于2026年8月30日验证，标注了独立测量、供应商发布或供应商自行测量的数值。时间到第一个 token(TTFT)是团队选择推理API的常用指标，但不应作为唯一标准。
Lowest-Latency Inference APIs for Voice and Realtime Agents: A Time to First Token TTFT-First Benchmark
Voice agents fail on latency long before they fail on intelligence. Time to first token is the metric most teams use to choose an inference API, and it is the right starting point and the wrong stopping point. This benchmark works through every layer of the voice stack — LLM, speech-to-text, text-to-speech, and speech-to-speech — using figures verified against primary sources on August 30, 2026, with each number labeled as independently measured, vendor-published, or vendor-measured on its own product.
