Why Soniox is the best speech-to-text API for Marathi AI voice agents

“Best” for Marathi voice agents isn’t just about top benchmark scores on clean audio, it’s about predictable, reliable behavior in real production systems.

To serve a potential market of over 83,000,000 Marathi speakers primarily in India, with speakers around the world, Marathi AI voice agents requires a deep understanding of regional accents and a predictable behavior in live production.

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

Deliver highly accurate transcription that keeps up with live Marathi 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 Marathi 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 Marathi language transcription starting at ~$0.12 per hour, Soniox makes it practical and cost-effective to deploy Marathi voice agents at massive scale, anywhere.

“As the leading provider of voicebots for automotive dealerships in Germany, we’ve faced significant challenges recognizing license plates accurately. Soniox has solved this problem with exceptional recognition of alphanumeric sequences, resulting in a much higher acceptance rate for our voicebot.”

Lowest-latency Marathi speech-to-text in practice

Low latency in voice agents isn’t achieved through a single optimization. It’s the result of an end-to-end system: streaming Marathi audio, real-time decoding, turn detection, and fast transcript delivery, working together so agents can respond naturally without waiting for full utterances.

The Soniox API is built for this. Developers can configure transcription behavior to match their agent’s requirements, balancing responsiveness, accuracy, and conversational timing in production.

Real-time Marathi streaming transcription

At the core is a real-time speech-to-text engine built for continuous conversational streams rather than offline batch requests.

Audio is streamed over a persistent connection, and transcripts are returned immediately as speech arrives. This enables Marathi voice agents and downstream LLM systems to begin reasoning and responding in real time, without waiting for the user to finish speaking.

Endpoint detection for Marathi conversations

Knowing when a user has finished speaking is just as important as knowing what they said.

Soniox includes built-in endpoint detection that identifies speech boundaries and emits end events. Marathi AI voice agents can use these events to decide when to respond without relying on fragile client-side silence timers.

The result is smoother turn-taking, fewer interruptions, and faster, more natural conversations.

Custom context with Marathi vocabulary

Transcription quality shouldn't drop when users mention specific Marathi brands or regional terms.

Soniox supports request-time context feature, allowing developers to inject domain-specific Marathi vocabulary, such as product names, jargon, entities, or topic knowledge, directly into the transcription stream.

This improves accuracy through simple configuration, without maintaining separate fine-tuned models for every agent or use case.

Precise multilingual transcription for 60+ languages including Marathi

Voice agents often need to handle users who switch between Marathi and other languages mid-sentence.

Soniox delivers highly-accurate real-time Marathi transcription and translation using a single model. Language identification happens automatically, keeping the conversation fluid without reconnecting the stream.

Data residency for industry compliance

For many production voice agents, data residency isn’t optional, it’s a compliance requirement. Regulated industries such as healthcare, legal, finance, and enterprise environments often require that speech and transcript data remain within specific geographic regions.

Soniox supports regional data residency, allowing voice agents to operate in regulated deployments while keeping customer data within required boundaries, all through the same real-time API.

Putting it all together

Voice agents demand more than high benchmark accuracy. They require speech recognition that is fast, predictable, multilingual, and reliable in real-world production conditions.

Soniox brings these capabilities together in a single real-time API: ultra-low latency streaming, built-in turn detection, context control, speaker-native accuracy for Marathi and across 60+ other languages, and regional data residency for regulated deployments.

If you're building Marathi voice agents that need to run at scale, Soniox is the speech layer designed for production.

Frequently asked questions about Soniox Speech-to-Text API for Marathi AI voice agents

What is the Soniox Speech-to-Text API for Marathi?arrow_downward

Soniox provides a real-time Marathi speech-to-text API designed for AI voice agents. It converts live Marathi 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 Marathi AI voice agents?arrow_downward

Yes. Soniox's multilingual AI speech models can easily handle real-time Marathi 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 Marathi speech-to-text API?arrow_downward

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

How does Soniox detect when Marathi-speaking users finish talking?arrow_downward

Soniox includes built-in endpoint detection that identifies speech boundaries in Marathi. 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 Marathi voice agents?arrow_downward

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