# 🌍 African Digits Recording Sprint
> Record numbers 0-9 in your African language.
1. Fill in your email. This is completely optional. We need this to track your progress for the prize.
__Note:__ You should record all numbers shown till the end. It does not count if you stop mid-way.
2. Choose your African language
3. Fill in the speaker metadata (age, gender, accent). This is optional but important to build better speech models.
4. You will see the image of a number __(this is the number you will record)__.
5. Fill in the word of that number (optional). You can leave this blank.
6. Click record and say the number in your African language.
7. Click ‘Submit’. It will save your record and go to the next number.
8. Repeat 4-7
9. Leave a ❤ in the Space, if you found it fun.
> Please Note: Record as many as times as possible (minimum of 20 and maximum of 200).
