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

“Best” for Urdu 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 230,000,000 Urdu speakers across Pakistan, India, and beyond, Urdu AI voice agents requires a deep understanding of regional accents and a predictable behavior in live production.

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

  • Deliver highly accurate transcription that keeps up with live Urdu 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 Urdu 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 Urdu language transcription starting at ~$0.12 per hour, Soniox makes it practical and cost-effective to deploy Urdu 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.”
