## How the top Gladia alternatives compare

The top 6 in depth: where each alternative ranks across the Speech-to-text APIs field we track, which use cases it takes from Gladia, and what switching gives up.

### 1. Deepgram

Among the 43 speech-to-text tools we track, Deepgram has the 26th-widest language coverage.
Our use-case verdicts have Deepgram ahead of Gladia for call centers, developers, medical and voice agents and matches it for dictation and self-hosted.
Seen from the other side, Gladia vs Deepgram: ~2× the languages.
Deepgram lists $0.0043 per audio-minute (batch), verified July 2026.

**Why teams switch (Call Centers):** For high-volume call center transcription, per-minute batch cost is the dominant factor. Deepgram charges 0.004 per audio minute versus Gladia's 0.010, making Deepgram 2.5 times cheaper at the base rate. On diarization, Gladia includes it in the base price, but Deepgram's total with diarization added is 0.006 per minute, still 40% cheaper than Gladia's base rate. Stacking both diarization and PII redaction brings Deepgram to 0.008 per minute, still below Gladia's base rate. Deepgram also supports higher concurrency at 50 REST and 150 websocket connections versus Gladia's 25 async and 30 real-time, which matters at peak call volumes. Both tools support sentiment analysis. The cost advantage at scale is decisive. [Call Centers verdict](https://www.versusref.com/stt/deepgram-vs-gladia/)

**Overall verdict:** Deepgram wins four use cases to Gladia's one, and the facts explain why. On price, Deepgram charges 0.004 dollars per audio minute for batch and 0.005 for streaming, versus Gladia's 0.010 and 0.013 respectively, making it the clear cost leader for call centers, medical, and high-volume developer workloads. For developers, Deepgram also offers SDKs in six languages including Go, Java, and Rust, compared to Gladia's two. In medical and call-center contexts, diarization and PII redaction matter: Deepgram provides both, though as add-ons, while its base streaming concurrency of 150 websocket connections far exceeds Gladia's 30. Gladia takes the meetings use case on the strength of its 3.23 percent third-party WER and 101-language coverage, but that single win cannot overcome Deepgram's broader price and platform advantages.

Deepgram cost: Published rates: batch $0.0043/min · streaming $0.0048/min, verified Jul 20, 2026.

| Monthly volume | Batch bill | Streaming bill |
| --- | --- | --- |

### 2. AssemblyAI

Among the 43 speech-to-text tools we track, AssemblyAI has the 12th-widest language coverage - a fit for multilingual and localization projects.
Head-to-head, AssemblyAI takes call centers, developers, meetings and voice agents from Gladia and matches it for dictation, medical and self-hosted.
Its published rate is $0.0035 per audio-minute (batch), verified July 2026.

**Why teams switch (Call Centers):** For high-volume call center transcription, per-minute batch cost is the dominant factor. AssemblyAI charges $0.0035 per audio minute versus Gladia at $0.010167 per audio minute, meaning Gladia costs nearly 3x more at scale. On speaker diarization, AssemblyAI adds a small extra per-minute charge of about $0.000333 per audio minute, while Gladia includes diarization in its base rate, but even with that add-on, AssemblyAI's total per-minute cost remains well below Gladia's base price. PII redaction is a paid add-on for AssemblyAI at about $0.001333 per audio minute but is included in Gladia's rate, yet again AssemblyAI's all-in cost stays lower. Concurrency seals the advantage: AssemblyAI supports 200+ concurrent async jobs versus Gladia's 25, which is critical for high call volumes. [Call Centers verdict](https://www.versusref.com/stt/assemblyai-vs-gladia/)

**Overall verdict:** AssemblyAI takes the overall edge over Gladia, winning on call centers, developers, meetings and voice agents. Compare the two on the use cases you care about before deciding.

AssemblyAI cost: Published rates: batch $0.0035/min · streaming $0.0075/min, verified Jul 20, 2026.

| Monthly volume | Batch bill | Streaming bill |
| --- | --- | --- |
| 1K min/mo | $3.50 | $7.50 |
| 10K min/mo | $35 | $75 |
| 100K min/mo | $350 | $750 |

### 3. OpenAI Whisper (API)

Among the 43 speech-to-text tools we track, OpenAI Whisper (API) has the 21st-widest language coverage.
In our published verdicts, OpenAI Whisper (API) beats Gladia for developers and self-hosted and matches it for call centers and dictation.
The reverse angle matters too - Gladia vs OpenAI Whisper (API): ~2× the languages.
Published pricing starts at $0.006 per audio-minute (batch), verified July 2026.

**Why teams switch (Self-Hosted):** For self-hosted deployment on your own hardware, the two most important factors are the self-host option and the model weights license. OpenAI Whisper's weights are released under the MIT license, making them freely usable on any hardware. Gladia explicitly supports a self-host option as well, but no open weights license is published for it. Since the use case specifically involves running an open-weight model on your own hardware, OpenAI Whisper is the only tool here with verified open model weights under a permissive license. Gladia offers on-premises deployment, but without open weights, users remain dependent on Gladia as a vendor even in self-hosted scenarios. [Self-Hosted verdict](https://www.versusref.com/stt/gladia-vs-whisper/)

**Overall verdict:** Gladia wins three use cases outright by delivering capabilities that OpenAI Whisper (API) simply cannot match at the API level. For Medical workflows, Gladia offers built-in speaker diarization and PII redaction included in the service, whereas OpenAI Whisper (API) provides neither. For Meetings, those same features combine with a lower third-party benchmark WER of 3.23% versus 4.06%, plus support for 101 languages against 57. For Voice Agents, Gladia provides a websocket streaming API with vendor-claimed 300 ms latency, while OpenAI Whisper (API) has no streaming option. OpenAI Whisper (API) counters with a lower batch price of $0.006 per minute versus $0.010, and open model weights under an MIT license enabling self-hosting, earning it the Developer and Self-Hosted cases. However, Gladia's breadth of built-in intelligence and real-time capabilities carry the overall comparison.

OpenAI Whisper (API) cost: Published rates: batch $0.006/min, verified Jul 20, 2026.

| Monthly volume | Monthly bill (batch) |
| --- | --- |
| 1K min/mo | $6 |
| 10K min/mo | $60 |
| 100K min/mo | $600 |

Among the 43 speech-to-text tools we track, Amazon Transcribe has the 3rd-widest language coverage - a fit for multilingual and localization projects.
Seen from the other side, Gladia vs Amazon Transcribe: ~10% fewer languages.
Amazon Transcribe lists $0.006 per audio-minute (batch), verified July 2026.
