Unfortunately, this is not possible right now since this validation is performed upon submission and therefore cannot be customized.
However, you could use a reCaptcha field instead (by enabling this feature in your current captcha field)
When a reCaptcha field has an invalid entry, it will be shown again (without a message) to re-enter the correct value. Also, you can find here other captcha widgets you can use in your form.
Hope this helps.
