How the top Speechmatics alternatives compare
A closer look at the top 6: each Speechmatics alternative's standing among Speech-to-text APIs peers, its verdict record against Speechmatics, and the trade-offs of leaving.
1. Deepgram
Among the 43 speech-to-text tools we track, Deepgram has the 26th-widest language coverage.
In our published verdicts, Deepgram beats Speechmatics for medical and voice agents and matches it for dictation and self-hosted.
The reverse angle matters too - Speechmatics vs Deepgram: ~10% more languages.
Published pricing starts at $0.0043 per audio-minute (batch), verified July 2026.
Why teams switch: Both tools offer a HIPAA BAA and SOC 2 Type II certification, so they tie on the two heaviest compliance attributes. The deciding factor is PII redaction, which carries a weight of 4 out of 5. Deepgram offers PII redaction as a paid add-on at $0.002 per audio minute, while Speechmatics does not offer PII redaction at all. In a clinical transcription context where protecting patient data is critical, having PII redaction available at any price is meaningfully better than having no option. Both tools also support custom vocabulary and self-hosting. The margin is narrow because Speechmatics matches on most other attributes, but the absence of PII redaction is a concrete gap on a heavily weighted criterion.
Medical verdict →
Overall verdict: Deepgram wins two use cases outright, medical and voice agents, compared to Speechmatics winning one. In medical, PII redaction as a paid add-on at 0.002 dollars per audio minute gives Deepgram a compliance tool Speechmatics lacks entirely, and HIPAA BAA support is shared by both. For voice agents, Deepgram's claimed streaming latency of 300 ms and a broader SDK roster covering Go and Java alongside Python and JavaScript make it the stronger real-time integration choice. Speechmatics takes meetings on the strength of its 4.05 percent third-party WER versus Deepgram's 5.18 percent, but that single win does not overcome Deepgram's lead in the higher-growth, higher-value segments of medical and real-time voice.

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.
In our published verdicts, AssemblyAI beats Speechmatics for medical, meetings and voice agents and matches it for dictation and self-hosted.
The reverse angle matters too - Speechmatics vs AssemblyAI: about half the languages.
Published pricing starts at $0.0035 per audio-minute (batch), verified July 2026.
Why teams switch: Both tools offer a HIPAA BAA, SOC 2 Type II, custom vocabulary, and self-host options, so those attributes do not separate them. The deciding factor is PII redaction, weighted 4 out of 5. AssemblyAI provides PII redaction as a paid add-on at about $0.08 per hour, while Speechmatics does not offer PII redaction at all. In a clinical setting under US healthcare privacy law, the ability to automatically redact patient identifiers is a meaningful compliance capability. Speechmatics simply cannot match it. That absence is a genuine gap for this use case, even though its batch pricing at $0.00215 per audio minute is lower than AssemblyAI's $0.0035.
Medical verdict →
Overall verdict: AssemblyAI takes the overall verdict by winning three use cases: Medical, Meetings, and Voice Agents. In Medical, it offers PII redaction as a paid add-on and includes a HIPAA BAA, while Speechmatics has no PII redaction capability at all. In Meetings, AssemblyAI supports 99 languages versus Speechmatics at 56, giving broader coverage for global calls. For Voice Agents, AssemblyAI posts a 3.02% third-party WER against Speechmatics at 4.05%, and supports 200 or more concurrent async jobs compared to Speechmatics at 50 real-time sessions, meaning it handles accuracy and scale better for live agent workloads. Speechmatics counters with lower batch pricing at about $0.13 per hour versus AssemblyAI at about $0.21 per hour, plus published volume discounts, giving it the edge for Call Centers and developer cost-sensitivity. The use-case wins, however, sit with AssemblyAI.
