Handle mid-sentence language switching in Serbian

In the real world, people often blend languages within a sentence or phrase. A user might say "Posle meeting-a ti forwardujem onaj email.", mixing Serbian and English. Soniox keeps up, instantly detecting language changes and transcribing every word in the correct language.

"It’s the first model we’ve used that actually understands Hinglish. Switching mid-sentence just works."

Prakash N,
Co-Founder & Director at Tevatel

Capture alphanumerics exactly as spoken in Serbian

From phone numbers and email addresses to reference IDs and license plates, Soniox recognizes alphanumeric speech with precision — even when spelled out in Serbian.

Every digit. Every character. In real time.

"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."

Dr. Steven Zielke,
Founder & CEO of mobilApp

Detect when a speaker has finished speaking

Soniox goes beyond basic silence detection.

Using advanced conversational endpointing, the system understands tone, meaning, and speech flow to determine when a speaker is actually finished — not just when they pause.

The result:

Faster agent responses
More natural turn-taking
Lower latency in live systems

"It’s so fast, captions appear before people even finish talking. Zero lag. No buffering. Nothing."

Dag-Inge Aas,
Head of AI at Tana

View real-time translation docs

Serbian is spoken by over 12 million people worldwide — across Serbia, Bosnia and Herzegovina, Montenegro, and beyond. For years, Serbian speech-to-text has fallen short, failing at fundamentals like accurate and reliable recognition, multiple languages, and alphanumerics. It converted Serbian audio into words, but the words lacked meaning and context.

Soniox reimagined everything Serbian speech-to-text got wrong. You can speak naturally, switch languages mid-sentence, spell out codes and names, or ask for instant Serbian translation, all in real-time. Soniox doesn’t just transcribe Serbian speech – it understands it.
