Master your English accent with precision.
Thorough helps you speak clearer, more natural English so you can feel confident in interviews, meetings, and everyday conversations.
With Thorough, you simply write or paste any English sentence, record yourself saying it, and instantly receive detailed feedback on your pronunciation.
How it works
1. Choose any sentence in English — from work emails, presentations, job interviews, or daily conversation.
2. Record yourself.
3. Get an instant score that shows how close you sound to a native speaker.
Thorough analyzes your speech at every level:
Overall accent score
Score per word
Score per phoneme (like /θ/, /ɪ/, /ʌ/, etc.)
You’ll know exactly which sounds are holding you back and how to fix them.
Why it works
Non-native speakers often struggle with English sounds that don’t exist in their language. Thorough identifies these problem areas automatically, helps you practice them, and tracks your progress over time.
Made for your career
Whether you're preparing for a remote job, aiming to move abroad, or wanting to sound more confident at work, clear pronunciation is a major advantage.

Speak better. Sound confident. Unlock new opportunities.
