Built for

Training and evaluating speech models that must handle real Serbian speech:

  • Automatic speech recognition (ASR / STT)
  • Text-to-speech & voice synthesis prosody
  • Voice agents and IVR for Serbia
  • Speaker diarization & turn-taking models
  • Speech LLM / audio-understanding fine-tuning

Why conversational data?

Models trained on read speech consistently underperform on spontaneous audio. Disfluencies, overlap, and natural speech rates aren’t in the training distribution. This dataset closes that gap for Serbian. Read more in our guide to conversational vs. scripted speech data.

FAQ

Frequently asked questions

What does the Serbian speech dataset include?

1,500 hours of spontaneous two-person conversations from 150 vetted native speakers recorded in Serbia, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.

What makes Serbian hard for speech recognition?

Serbian is written in both Cyrillic and Latin, so transcripts need one fixed convention. It has pitch accent and vowel length that spelling doesn't show, and it's close enough to Croatian and Bosnian that a model needs native Serbian data to get the differences right.

Is there free Serbian speech data?

Yes, ParlaSpeech-RS, Mozilla Common Voice and FLEURS are free for commercial use. This dataset is spontaneous two-person conversation recorded in Serbia, with speaker metadata, one channel per speaker and signed commercial-use consent.

Can I use this Serbian dataset commercially?

Yes. The dataset is licensed for commercial use, including training ASR, TTS, and other voice-AI models. Every speaker has signed explicit commercial-use consent, and we provide the full consent chain for your legal review.

How much does the Serbian speech dataset cost?

Pricing is $75 per hour of audio. Volume discounts are available for full-dataset and multi-language purchases. Contact us for a quote.

Can I evaluate samples before buying?

Yes. Request samples with your company email, and we'll email you representative audio files and matching transcripts so your team can audit quality before committing.
