Voice Studio
What the studio does
01Numbers, dates, money
“21 hryvnia”, “22 rubles 50 kopecks”, “March 3rd, 2026” — digits are expanded into words with the right endings before the voice reads them.
Stress marks in Russian and Ukrainian
Stress is placed automatically, so names and homographs sound like a native speaker reads them.
Reading modes
Calm, normal and fast pace; a pause after every sentence for lessons and meditations.
AI label in every file
ID3 tags and an inaudible watermark. Anyone can check a file on the Check audio page.
API on Pro
One POST request returns an mp3. Long texts go through a job queue.
