Side-by-Side Comparison
How AssemblyAI, Deepgram compare across the features that matter most.
| Feature | AssemblyAI | Deepgram |
|---|---|---|
| Category | Speech-to-text & audio intelligence API | Voice AI: STT, TTS & agent APIs |
| Strengths | High accuracy, audio intelligence, entity precision | Low-latency streaming, high-volume batch |
| Deployment | Cloud-native | Cloud, VPC and on-premises (Docker/Kubernetes) |
| Real-time latency | Sub-second | Sub-300ms turn detection (Flux) |
| Audio intelligence | Built-in (sentiment, summarization, diarization) | Keyword boosting, custom model training |
| Voice agents | Voice Agent API (STT+LLM+TTS) | Voice Agent + Flux turn-detection |
| Compliance / on-prem | Cloud only | On-prem for HIPAA / air-gapped |
| Best for | Feature-rich voice agents, minimal infra | Ultra-low latency and on-prem at scale |
KLYROO Test
Our comparison philosophy is to evaluate tools with consistent tasks and realistic workflows across categories such as writing, coding, research, reasoning, image generation, summarization and data analysis. Where we have not run a controlled head-to-head, we label the assessment clearly: this comparison is an editorial evaluation based on documented features and available evidence. We never invent benchmark numbers.
Which One Should You Choose?
- Choose AssemblyAI for high accuracy plus built-in audio intelligence with minimal infrastructure.
- Choose Deepgram for sub-300ms latency, on-premises deployment or the lowest cost at extreme scale.
- Both offer robust Python/Node SDKs and OpenAI-style WebSocket streaming.
