# Deepgram Keyterm Prompting Now Available for Voice AI Assistants

### 20, Apr 2026

Voice AI Assistants now support [Deepgram Keyterm Prompting](https://developers.deepgram.com/docs/keyterm) for Nova-3 and Flux STT models. Define up to 100 domain-specific terms and Deepgram prioritizes them during transcription, improving Keyword Recall Rate by up to 90%.

### What's new

* **Keyterm Prompting support:** Define domain-specific terms for Nova-3 and Flux at the assistant level, with no model retraining needed.
* **Up to 100 keyterms per request:** Product names, acronyms, multi-word phrases, proper nouns, and industry-specific vocabulary.
* **Mono and multilingual coverage:** Works with Nova-3 standard, Nova-3 multilingual, and Flux.
* **On-network processing:** Keyterm matching runs inside Telnyx-hosted Deepgram models, keeping audio and inference on the same private backbone.
* **Mission Control configuration:** Set keyterms directly in your Voice AI Assistant settings with no API call required.

### Why it matters

* Generic STT accuracy breaks down on specialized vocabulary. Brand names, SKUs, and clinical terms get misrecognized, breaking conversation flow and eroding caller trust.
* Keyterm Prompting boosts Keyword Recall Rate up to 90%, so the terms that define your use case come through correctly on the first pass.
* Capitalization and formatting from your keyterm list carry through to the transcript. Your output reflects your terminology, not a generic phonetic approximation.
* No retraining, no custom models. Add a list of terms and get better accuracy immediately.

### Example use cases

* Healthcare voice agents that need to recognize drug names, procedure codes, and clinical terminology accurately.
* Sales and support bots handling product catalogs where SKUs, model numbers, and brand names are critical.
* Financial services assistants transcribing ticker symbols, fund names, and regulatory terms.
* Logistics agents capturing shipper names, carrier codes, and location identifiers without errors.

### Getting started

1. Log in to Mission Control, go to AI, then Assistants, and select your assistant.
2. Open the **Voice** tab and scroll down to **Transcription**.
3. Select **Nova-3** or **Flux** as your STT model.
4. Enter your terms in the **Keyterm Boost** field.
5. Test a live call and confirm your target terms appear correctly in the transcript.

**Learn more** in the [Deepgram Keyterm Prompting docs](https://developers.deepgram.com/docs/keyterm) or the [Telnyx AI Assistants documentation](https://developers.telnyx.com/docs/inference/ai-assistants/transcription-settings).
