Pricing
FreemiumDeepgram offers $200 in free credit on signup with no credit card required, usable across any service (Speech-to-Text, Text-to-Speech, Voice Agent API, and Audio Intelligence) and credits do not expire. Pay-As-You-Go pricing for Nova-3 starts at approximately $0.0043/minute for mono pre-recorded transcription (roughly $0.0052/minute for multi-channel/stereo audio) and $0.0077/minute for real-time streaming transcription, with rates dropping to around $0.003/minute at high volume. The Voice Agent API, which bundles speech-to-text, LLM orchestration, and text-to-speech, is priced at $4.50/hour, or roughly $0.08/minute (with a lower bring-your-own-LLM rate around $0.07/minute). Flux text-to-speech is free to use through September 12, 2026 (up to 45 concurrent streaming connections globally, 5 in EU/AU), with standard pricing applying starting September 13, 2026. A Growth tier offers roughly 15-20% discounted rates in exchange for a $4,000+ annual prepayment commitment. On-premise and self-hosted deployment for security, compliance, or latency-sensitive workloads requires a custom Enterprise agreement.
FreemiumNabla does not publish exact pricing on its official website; the primary calls-to-action are a free trial (via app.nabla.com) and "Talk to our team" for enterprise sales. Third-party sources consistently report a free tier with usage limits, with paid individual/clinician plans starting around $119/month per provider and higher tiers reported near $239/month per provider. Larger health-system deployments — Nabla's core market, spanning 130+ organizations — are sold via custom enterprise contracts with volume-based pricing, with independent estimates placing typical enterprise rates in the $150-$400/month per provider range depending on scale, EHR integration depth, and features. Exact costs require a sales conversation with Nabla.

Summary
Voice AI infrastructure for speech-to-text, text-to-speech, and voice agents
Ambient AI that turns patient visits into clinical notes, dictation, and coding — right inside the EHR
Deepgram Pros & Cons
Pros
- Nova-3 delivers industry-leading accuracy with a 47-54% lower word error rate than competing models
- Voice Agent API eliminates the need to stitch together separate STT, LLM, and TTS services
- $200 free credit with no credit card required is one of the more generous evaluation tiers in the category
- Billing by the exact second with transparent, published per-minute rates avoids hidden pricing surprises
- Proven at massive scale: 50,000+ years of audio processed, 1 trillion+ words transcribed, used by NASA, Spotify, and Twilio
Cons
- Growth tier discounted pricing requires a $4,000+ annual prepayment commitment
- On-premise/self-hosted deployment requires a custom enterprise agreement rather than self-serve setup
- Steeper learning curve than simpler transcription apps, built for developers rather than non-technical dashboard users
- Multi-channel (stereo) audio transcription costs meaningfully more than mono per-minute rates
- Flux TTS pricing shifts from free to standard rates after September 12, 2026, which teams building now should plan around
Nabla Pros & Cons
Pros
- Fast note generation, roughly five seconds, that closely mirrors real clinical documentation in independent tests
- Deep native integration with Epic and other major EHRs rather than copy-paste workflows
- Broad specialty and language coverage suited to large, diverse health systems
- Strong compliance posture (HIPAA, SOC 2 Type 2, ISO 27001, GDPR) with configurable data retention
- Backed by peer-reviewed evidence, including a NEJM AI randomized trial showing documentation-time reductions
- Combines documentation, dictation, and coding in one platform instead of separate point tools
Cons
- Pricing isn't published; individuals and smaller practices must go through a sales conversation or rely on third-party estimates to budget
- Primarily built for hospitals and health systems, so solo clinicians and small practices may find it less tailored than SMB-focused scribes
- Relies on ambient recording, so encounters where a patient or clinician can't or won't be recorded aren't well supported
- Some independent reviews note limited customization and quality drop-off on complex, multi-problem visits
- Mobile app store ratings are mixed and based on a relatively small number of reviews compared to the platform's overall clinician base
