## How the top AssemblyAI alternatives compare

Beyond the ranked cards: how the top 6 AssemblyAI alternatives place in the Speech-to-text APIs field, where each one wins in our published verdicts, and what AssemblyAI still holds over it.

### 1. Deepgram

Among the 43 speech-to-text tools we track, Deepgram has the 26th-widest language coverage.
Head-to-head, Deepgram holds AssemblyAI to a tie for dictation, medical and self-hosted.
Before switching, weigh what stays behind - AssemblyAI vs Deepgram: ~2× the languages.
Its published rate is $0.0043 per audio-minute (batch), verified July 2026.

**Overall verdict:** AssemblyAI wins three use cases outright (Call Centers, Developers, Meetings) and ties the remaining three. The core reasons are accuracy, streaming speed, and cost efficiency. In third-party benchmarks, AssemblyAI records a 3.02% word error rate versus Deepgram's 5.18%, a meaningful gap that drives its edge in call center and meetings transcription. On streaming, AssemblyAI claims 150 ms latency against Deepgram's 300 ms, which matters for real-time developer applications. For batch work, AssemblyAI's per-minute rate is lower than Deepgram's, and its diarization add-on is also cheaper per minute. AssemblyAI supports 99 languages versus Deepgram's 50, broadening its appeal. Deepgram offers a larger free-tier credit ($200 versus $50) and a wider SDK selection, but those advantages were not enough to flip any use case.

### 2. OpenAI Whisper (API)

Among the 43 speech-to-text tools we track, OpenAI Whisper (API) has the 21st-widest language coverage.
Head-to-head, OpenAI Whisper (API) takes self-hosted from AssemblyAI and matches it for dictation.
Before switching, weigh what stays behind - AssemblyAI vs OpenAI Whisper (API): ~2× the languages.
Its published rate is $0.006 per audio-minute (batch), verified July 2026.

**Why teams switch (Self-Hosted):** For self-hosted deployment on your own hardware, both heavily weighted attributes favor OpenAI Whisper. AssemblyAI offers an on-premises option, but it is an enterprise arrangement requiring a contract. OpenAI Whisper model weights are openly available under an MIT license, meaning anyone can run them locally without negotiating with a vendor. The MIT license is the decisive factor: it gives full freedom to deploy, modify, and distribute the model on any hardware with no restrictions. AssemblyAI publishes no model weights license, so its self-host path is a vendor-controlled arrangement rather than a true open-weight deployment. [Self-Hosted verdict](https://www.versusref.com/stt/assemblyai-vs-whisper/)

**Overall verdict:** AssemblyAI wins four of six use cases, and the facts behind each win are concrete. Its third-party word error rate of 3.02% beats OpenAI Whisper API's 4.06%, giving it an accuracy edge that matters for developers, medical transcription, and meetings. For medical and compliance-sensitive work, AssemblyAI offers speaker diarization as a paid add-on while Whisper API offers none at all, and AssemblyAI supports self-hosting for on-prem deployments where Whisper API cannot. For voice agents, AssemblyAI is the only option with a websocket streaming API, vendor-claimed at 150 ms latency. Its batch pricing of $0.0035 per audio minute also undercuts Whisper API's $0.006 per audio minute. Whisper API takes the self-hosted use case because its model weights carry an MIT license, but that single win cannot overcome AssemblyAI's broader feature depth and lower base pricing.

### 3. ElevenLabs Scribe

Among the 43 speech-to-text tools we track, ElevenLabs Scribe has the 19th-widest language coverage.
Head-to-head, ElevenLabs Scribe takes developers and voice agents from AssemblyAI and matches it for dictation.
Before switching, weigh what stays behind - AssemblyAI vs ElevenLabs Scribe: ~10% more languages.
Its published rate is $0.0037 per audio-minute (batch), verified July 2026.

**Why teams switch (Developers):** On batch pricing, ElevenLabs Scribe charges about $0.003667 per audio minute versus AssemblyAI at $0.0035 per audio minute, making AssemblyAI slightly cheaper. Both tools offer Python and JavaScript/Node SDKs and WebSocket streaming APIs, so those attributes are level. Both provide word-level timestamps. On supported audio formats, AssemblyAI covers 30+ formats compared to Scribe's 9 listed formats, giving AssemblyAI an edge there. However, ElevenLabs Scribe posts a meaningfully better third-party WER of 2.18% versus AssemblyAI's 3.02%, which matters for transcription quality in production products. The batch price gap is small at about 5%, SDKs and streaming are tied, and Scribe's accuracy advantage tilts the overall developer value proposition narrowly in its favor. [Developers verdict](https://www.versusref.com/stt/assemblyai-vs-elevenlabs-scribe/)

**Overall verdict:** AssemblyAI wins three use cases to ElevenLabs Scribe's two. In Call Centers, it offers 200+ concurrent async jobs versus ElevenLabs Scribe's 8 concurrent requests, a massive throughput advantage. In Medical, AssemblyAI includes a HIPAA BAA as standard while ElevenLabs Scribe restricts it to enterprise plans. In Self-Hosted, AssemblyAI offers an on-premises deployment option that ElevenLabs Scribe does not publish. ElevenLabs Scribe holds a narrower third-party WER of 2.18% versus AssemblyAI's 3.02%, and wins Developers and Voice Agents, but those two wins cannot overcome AssemblyAI's advantages in compliance, scale, and deployment flexibility.

ElevenLabs Scribe cost: Published rates: batch $0.0037/min · streaming $0.0065/min, verified Jul 20, 2026.

| Monthly volume | Batch bill | Streaming bill |
| --- | --- | --- |
| 1K min/mo | $3.67 | $6.50 |
| 10K min/mo | $36.67 | $65 |
| 100K min/mo | $366.70 | $650 |

### 4. Speechmatics

Among the 43 speech-to-text tools we track, Speechmatics has the 24th-widest language coverage.
In our published verdicts, Speechmatics beats AssemblyAI for call centers and developers and matches it for dictation and self-hosted.
The reverse angle matters too - AssemblyAI vs Speechmatics: ~2× the languages.
Published pricing starts at $0.0022 per audio-minute (batch), verified July 2026.

**Why teams switch (Call Centers):** For call center workloads at scale, batch transcription rate is the dominant cost driver. Speechmatics charges $0.00215 per audio minute versus AssemblyAI at $0.0035 per audio minute, a difference of roughly 39% per minute that compounds heavily at high volume. On speaker diarization, Speechmatics includes it in the base rate while AssemblyAI adds roughly $0.000333 per audio minute, widening the total cost gap further for diarized call recordings. AssemblyAI counters with PII redaction as a paid add-on, which Speechmatics lacks entirely, and AssemblyAI's concurrency ceiling of 200 or more async jobs is notably higher than Speechmatics' 50 real-time sessions. Sentiment analysis is available on both. Even so, the combination of a lower batch price and included diarization tips the scale.

### 5. Gladia

Among the 43 speech-to-text tools we track, Gladia has the 4th-widest language coverage - a fit for multilingual and localization projects.
In our published verdicts, Gladia matches AssemblyAI for dictation, medical and self-hosted.
Its published rate is $0.0102 per audio-minute (batch), verified July 2026.
