Built for
Training and evaluating speech models that must handle real Turkish speech:
- Automatic speech recognition (ASR / STT)
- Text-to-speech & voice synthesis prosody
- Voice agents and IVR for Turkey
- 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 Turkish. Read more in our guide to conversational vs. scripted speech data.

Frequently asked questions
What does the Turkish speech dataset include?
2,000 hours of spontaneous two-person conversations from 200 vetted native speakers recorded in Turkey, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Turkish hard for speech recognition?
Turkish stacks suffixes onto words ("evlerimizden" means "from our houses"), and vowel harmony changes those suffixes. Spoken Turkish also softens or drops sounds, and the soft "ğ" mostly just lengthens the vowel before it, so spelling and sound don't line up neatly.
Is there free Turkish speech data?
Yes, Common Voice Scripted Speech, Common Voice Spontaneous Speech and FLEURS are free for commercial use. The IARPA Babel Turkish Language Pack needs a paid license. This dataset is spontaneous two-person conversation recorded in Turkey, with speaker metadata, one channel per speaker and signed commercial-use consent.
Can I use this Turkish 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 Turkish 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.
