CAPABILITIES
A Complete System,
From Audio to Official Transcripts
The Most Accurate Greek ASR
Our custom model, is not a fine-tuned version of a generic model. It was trained from the ground up on Greek audio with our proprietary dataset that covers a huge variety of sectors.
-
Industry-leading accuracy - purpose-trained on 150,000+ hours of real Greek audio, not adapted from generic models
-
Speaker Diarization - automatically identifies and labels each speaker
-
Custom Dictionaries - legal, medical, technical, municipal terms
-
Real-time & Batch - live transcription or recorded file processing
-
Auto-punctuation - structured output ready for editing, not raw word dumps
-
VAD - intelligent speech segmentation, handling pauses and background noise
WHY GSTT IS DIFFERENT
Built for Greek, not adapted- Trained from scratch on Greek audio - not a multilingual model with a Greek layer on top.
720,000+ hours of real audio-Parliament, sessions, news, field recordings - not synthetic or crowd-sourced data.
Continuous fine-tuning-
Every deployment improves the model. Your domain data trains your model.
Proven at institutional scale- Hellenic Parliament, Ministry of Interior - 3+ years in live production.
THE PROBLEM
Manual Transcription
Is Costing You Time, Money, and Compliance
Every day, Greek public bodies, courts, law firms, and enterprises produce hours of spoken proceedings. Turning speech into usable, searchable text still relies on manual transcription: slow, expensive, and error-prone.
⚠ THE CURRENT PROBLEM
International tools fail at Greek
Generic cloud APIs are not trained on Greek morphology, dialects, parliamentary vocabulary, or legal terminology. The result: poor accuracy requiring extensive correction, or continued dependence on manual labour.
✓ THE GSTT SOLUTION
Trained from the ground up for Greek
GStT is not a foreign tool with a Greek language pack. It is a speech-to-text platform engineered exclusively for the Greek language, by a Greek company, trained on parliamentary sessions, TV Shows, meetings, councils, and real-world recordings.

STEP 04
Deliver
Audio from any source -meeting rooms, courtrooms, call centres, field recordings.
The VAD engine segments the audio, and the ASR model transcribes each segment with speaker labels.
Automatic grammar correction, punctuation, and optional translation. Editors review and approve via the management platform.
Final transcripts exported as PDF/DOCX, stored in the searchable archive, or pushed to downstream systems via API.
