What a Hungarian voice agent needs from speech-to-text

To serve more than 13,000,000 Hungarian speakers primarily in Hungary, with speakers around the world, a Hungarian voice agent has to handle regional accents and behave predictably in live production.

A speech-to-text system for Hungarian voice agents should:

Deliver highly accurate transcription that keeps up with live Hungarian conversations.
Run with ultra-low latency, enabling real-time LLM processing and fast responses.
Reliably detect end-of-turn speech so agents respond at the right moment.
Perform in real-world conditions with noise, accents, interruptions, and multilingual speech.
Scale economically, with pricing that works for high-volume deployments.

Soniox is built around these requirements from the ground up, delivering fast, reliable speech recognition for voice agents for Hungarian and all other 60+ supported languages. One unified model supports true multilingual and language-switching speech, without changing configurations, switching models, or restarting streams.

With real-time Hungarian language transcription starting at $0.12 per hour, Soniox makes it practical and cost-effective to deploy Hungarian voice agents at massive scale, anywhere.

“As Germany’s leading voicebot provider for automotive dealerships, Soniox has transformed our recognition of customer IDs and alphanumerics, driving much higher voicebot acceptance rates.”

Why it works

Voice agents need speech recognition that is fast, predictable, multilingual, and production-ready.

Soniox combines low-latency streaming, turn detection, context control, Hungarian accuracy, and regional deployment in one real-time API.

Build a Hungarian voice agent

If you tried our introduction demo above, you saw the voice loop in action: streaming speech-to-text, LLM reasoning, and streaming text-to-speech working together in real time. We put the same underlying architecture into an open-source reference app you can clone, run locally, and adapt to your own use case and style.

Get your Hungarian voice agent running

The Soniox Voice Agent demo is an open-source voice-to-voice assistant you can clone, run locally, and adapt to Hungarian. The default scenario is an appointment-booking agent for a fictional car repair shop, but the same architecture works for any voice agent (support, intake, scheduling, anything that needs to listen and speak).

How the voice loop fits together

Microphone audio runs through Silero VAD for barge-in detection, then into Soniox STT for streaming transcription with semantic endpoint detection. The transcript flows to an LLM, which streams its reply token by token straight into Soniox TTS. Soniox TTS is itself a real-time full-duplex streaming model: text flows in on the WebSocket while audio flows out on the same connection at the same time. It starts streaming back audio from the first few words, and as the LLM keeps producing tokens, Soniox keeps turning them into audio as they arrive. The user hears the reply as it forms, with no wait for the LLM to finish before the voice starts.

What's in the repo

Python server: orchestrates VAD, STT, LLM, and TTS, and holds the conversation state.
React frontend: captures mic audio in the browser and plays the agent's reply.
Twilio proxy (optional): connect the same agent to a phone number.

Get it running

Create an account on Soniox Console and generate your Soniox API key.
Clone Soniox Examples repo that contains apps/soniox-voice-bot-demo code and follow the READMEs in the /server and /frontend folders to install dependencies and set your API key.
Adapt the system prompt, STT language hints and TTS language to Hungarian. See STT language hints and TTS supported languages.
Start the server and the frontend, open it in your browser, and have a Hungarian conversation.

Learn more about the demo and all possible STT and TTS API configurations and concepts from our comprehensive docs page.

Plug Soniox into your framework of choice

If you don't want to wire up the voice loop yourself, and you're already using a popular voice-agent framework, Soniox plugs in as the STT and TTS through ready-made integrations.

Pipecat (voice-agent framework): drop in Soniox STT and TTS through the official STT and TTS packages.
LiveKit (real-time audio platform): use Soniox as the speech layer for LiveKit voice agents in the browser, on mobile, or over telephony.

Soniox also provides official integrations with LangChain, Twilio, n8n and other integrations.

Frequently asked questions

Which speech-to-text should I use for a Hungarian voice agent?

Use the Soniox real-time speech-to-text API, which is built for AI voice agents. It converts live Hungarian speech into text with low latency, supports streaming use cases, and works alongside more than 60 other languages without switching models or restarting the stream.

Is Soniox suitable for building Hungarian AI voice agents?

Yes. Soniox's multilingual speech model handles real-time Hungarian voice agent workflows, including streaming transcription, early token delivery, and endpoint detection for conversational turn-taking, all configurable through the API.

What makes Soniox a low-latency Hungarian speech-to-text API?

Soniox uses a real-time streaming architecture that processes Hungarian audio continuously and emits transcription results incrementally as speech arrives. This allows voice agents to begin processing Hungarian speech before an utterance is complete.

How does Soniox detect when Hungarian-speaking users finish talking?

Soniox includes built-in endpoint detection that identifies speech boundaries in Hungarian. Voice agents can use emitted end events to decide when to respond without relying on client-side silence timers.

Can I customize transcription behavior for Hungarian voice agents?

Yes. The Soniox API is configurable, allowing developers to adjust transcription behavior for Hungarian speech, including custom context for domain-specific vocabulary, eliminating the need for separate fine-tuned models.

Can Soniox handle language switching involving Hungarian within a conversation?

Yes. Soniox can recognize and transcribe speech when speakers switch between Hungarian and other supported languages mid-sentence or mid-conversation, without requiring stream restarts or language-specific routing.

Is Soniox suitable for regulated industries using Hungarian speech?

Yes. Soniox supports data residency for regulated environments such as medical and legal use cases, allowing Hungarian speech and transcript data to remain within required geographic regions while using the same real-time API.

Is Hungarian audio stored when using the Soniox API?

No. Hungarian audio is processed in real-time and kept in memory only. Soniox is designed for privacy-critical voice agent applications where speech data should not be stored by default.

How do developers get started with Hungarian speech-to-text in Soniox?

Developers can generate an API key on Soniox Console and start streaming Hungarian audio over WebSockets to Soniox immediately. The API integrates with common voice agent frameworks and real-time media pipelines.
