Introducing Design Voice Prompts

Nov 24, 2025

Last week, our team shipped something we’re really excited about, a brand-new Voice Prompt Designer that makes creating natural, expressive, and customizable voice interactions easier than ever.

Here’s what it can do:

🎨 Dynamic Personality Controls Choose from a variety of built-in voice personalities and watch your prompts instantly adapt tone, phrasing, and emotional nuance. No more flat or repetitive responses, each voice has its own style.

⚙️ Automatic Prompt Enrichment Start with a simple phrase like “drive-through pancakes” and hit Enrich Prompt. You’ll see the system build a full, expressive prompt that guides the LLM to sound more realistic and human.

🎧 Instant Voice Previews One click, and you can hear how each personality interprets the same interaction. Whether it’s friendly, calm, energetic, or quirky, the prompter fine-tunes the delivery to match the brand or experience you’re designing.

The result? Voice experiences that feel natural, delightful, and tailored, without manually crafting dozens of variations.

This unlocks a whole new level of creativity for teams building conversational AI. And honestly? Hearing an AI warmly welcome you to a fictional “Drive-Through Pancakes” might be the highlight of our week. 🥞
