This guide walks you through configuring Smallest AI as the TTS and STT provider in Dograh, an open-source platform for building and deploying voice agents. Dograh lets you swap speech providers independently — you can use Smallest AI for both TTS and STT, or mix providers as needed.

Prerequisites

Setup

1

Open the Models page

Navigate to https://app.dograh.com/workflow and click Models in the left sidebar.

2

Open the BYOK tab

In the AI Models Configuration section, click the BYOK tab at the top. This is where you configure third-party providers including Smallest AI.

3

Configure TTS (Voice tab)

Click the Voice sub-tab. Set Provider to Smallest AI and choose your Model:

  • lightning_v3.1 — standard pool with 217 voices across 12 languages
  • lightning_v3.1_pro — premium pool with curated American, British, and Indian voices at 44.1 kHz

Select a Voice from the dropdown (voices are scoped to the model), set the Language, and optionally adjust Speed (0.5–2.0).

Configure STT (Transcriber tab)

Click the Transcriber sub-tab. Set Provider to Smallest AI — the Model will be set to pulse automatically. Select your Language and enter your Smallest AI API key in the API Key(s) field.

Notes

  • Dograh routes TTS requests to wss://api.smallest.ai/waves/v1/tts/live and STT requests to wss://api.smallest.ai/waves/v1/pulse/get_text using the Pipecat service implementations under the hood.
  • For issues with the Smallest AI integration in Dograh, open an issue in the Dograh repository or contact us on Discord.
