Handle mid-sentence language switching in Swedish

In the real world, people often blend languages within a sentence or phrase. A user might say "Vi kan ta en quick sync efter lunch.", mixing Swedish 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 Swedish

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

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."

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

Separate and identify speakers in Swedish

Soniox performs real-time speaker separation and identification across 60+ languages, including Swedish.

Transcripts stay structured, searchable and easy to follow. Even in fast, overlapping, multi-speaker conversations.

"Live multilingual meetings finally sound natural, Soniox translates fluidly, in real-time."

View real-time translation docs

Swedish is spoken by over 10 million people worldwide — primarily in Sweden, with speakers around the world. For years, Swedish speech-to-text has fallen short, failing at fundamentals like accurate and reliable recognition, multiple languages, and alphanumerics. It converted Swedish audio into words, but the words lacked meaning and context.

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