What is the difference between the Vox AI Scoring Engine and the ETS Scoring Engine?
Two scoring options. One credit balance.
Vox AI is best for daily practice, repetition, and fast score checks. It costs fewer credits, so you can practice more often.
The ETS Engine is best for benchmark validation and final readiness checks. It uses licensed ETS® scoring technology and is the strongest option when you want the highest-confidence practice estimate.
Most users should practice regularly with the Vox AI Engine and use the ETS Engine when they want to confirm readiness before test day.
How do credits work?
Credits can be used for Vox AI or ETS scoring.
Credits are shared across both scoring options. You can use the same credit balance for
Vox AI scoring or
ETS Engine scoring.
- Vox AI: 1 credit per task, 2 credits per full test
- ETS Engine: 2 credits per task, 4 credits per full test
How fast do I get my score?
Scores appear in seconds.
Scores appear in seconds. Detailed feedback typically appears within a few minutes after scoring.
Why should I trust the scoring?
Licensed ETS technology is available.
My Speaking Score gives you two scoring options. Vox AI is built for frequent practice and fast feedback. The ETS Engine uses licensed ETS® scoring technology for benchmark scoring.
Practice scores are not official TOEFL scores, but they help you understand your current speaking level and what to improve before test day.
How accurate are the score estimates?
Use Vox for practice. Use ETS for benchmarking.
Score estimates are most useful when you use them as repeated evidence, not as a guarantee.
Vox AI is best for frequent practice because it helps you test changes quickly. The ETS Engine is best when you want a stronger benchmark estimate before test day.
No practice platform can guarantee your official TOEFL score, but scored practice can reduce guessing and help you prepare with clearer evidence.
Do I have to subscribe?
No monthly fees.
No. There are no monthly fees. You purchase credits only when you want scoring.
Do credits expire?
No expiration. No refunds.
No. Credits never expire and remain in your account until you use them. Due to our high-volume, low-cost services, all purchases are final and we do not offer refunds.
Will ETS see my identity or answers?
No TOEFL registration data is shared.
ETS does not receive your TOEFL registration information through this platform. My Speaking Score sends only the data required to generate practice scoring through the licensed ETS® scoring engine.
