Smallest AI Now Available in Dograh: Build Open-Source Voice Agents with Lightning TTS and Pulse STT

Harshita Jain
We believe Voice AI should be composable.
The orchestration layer shouldn't dictate your speech models. Your speech provider shouldn't dictate where you deploy. And your infrastructure shouldn't force trade-offs between performance, compliance, and flexibility.
That's why we're excited to announce Smallest AI's integration with Dograh. Developers can now use Smallest AI's speech models directly within Dograh's open-source voice agent platform, creating a fully customizable voice stack built around openness, choice, and performance.
With this integration, Dograh users can now power their agents using Smallest AI's speech stack:
Lightning v3.1 for ultra-low latency text-to-speech
Lightning v3.1 Pro for premium-quality voices
Pulse for real-time speech-to-text
The integration allows developers to combine Dograh's visual workflow builder and open architecture with Smallest AI's speech models to create responsive, production-ready voice experiences.
What is Dograh?
Dograh is an open-source Voice AI platform designed for building and deploying voice agents.
Think of it as a visual workflow builder for voice applications - similar to how automation tools like n8n simplify workflow creation, but purpose-built for voice agents and AI calling.
Built by exited founders and YC alumni, Dograh is focused on making voice infrastructure more accessible, flexible, and transparent.
Key capabilities include:
Visual workflow builder for voice agents
Self-hosted and cloud deployment options
Bring-your-own-model architecture
Support for speech-to-speech workflows
MCP-native integrations
Open-source flexibility and compliance controls
For teams building customer-facing voice systems, Dograh offers an alternative approach to closed voice agent platforms, giving developers greater control over infrastructure, data handling, and model selection.
Why This Integration Matters
Voice agents are only as good as the quality and responsiveness of their speech stack.
A typical voice workflow looks something like this:
User Speech → Speech-to-Text → LLM → Text-to-Speech → User
Every component contributes to the overall experience, but speech models often have the largest impact on latency and conversational quality.
By integrating Smallest AI into Dograh, developers can now combine an open voice orchestration layer with fast, production-ready speech models.
Open Architecture without Vendor Lock-In
One of Dograh's core principles is flexibility.
Developers can:
Use Smallest AI for both TTS and STT
Use Smallest AI for only one part of the stack
Mix and match providers depending on use case
This allows teams to optimize for quality, latency, cost, compliance, or deployment preferences.
Faster Development Cycles
Building voice agents traditionally requires stitching together multiple services, APIs, and infrastructure components. Dograh simplifies this process through a visual workflow builder, while Smallest AI provides plug-and-play speech capabilities.
The result is a faster path from prototype to production.
Available Smallest AI Models
Lightning v3.1
Lightning v3.1 is Smallest AI's low-latency text-to-speech model designed for real-time conversational applications.
It provides access to:
217 voices
Optimized streaming performance
Natural conversational speech
Lightning v3.1 Pro
Lightning v3.1 Pro is designed for teams that need higher-fidelity voice experiences.
It features:
Premium voice pool
Curated American, British, and Indian voices
44.1 kHz audio output
Pulse
Pulse is Smallest AI's real-time speech-to-text model.
It enables:
Streaming transcription
Low-latency speech recognition
Real-time conversational workflows
Pulse serves as the foundation for voice agents that need immediate understanding of user speech before generating responses.
Getting Started
Setting up Smallest AI in Dograh takes only a few minutes.
Step 1: Open the Models Configuration Page
Navigate to the Models section within Dograh's workflow builder.

Step 2: Configure Smallest AI for Text-to-Speech
Under the Voice configuration:
Select Smallest AI as the provider
Choose either Lightning v3.1 or Lightning v3.1 Pro
Select a voice
Choose a language
Adjust speech speed if required

Step 3: Configure Smallest AI for Speech-to-Text
Under the Transcriber configuration:
Select Smallest AI as the provider
Pulse will be selected automatically
Choose your language
Add your Smallest AI API key

Once configured, your Dograh agents can immediately begin using Smallest AI speech models.
