| ❌ Failed - Due to Noise | This outcome will occur if background noise detected | Re-record your paragraphs |
| ❌ Failed - Due to speech recognition | This outcome will occur if significant mismatch detected between the recording and the paragraph text (if accuracy is at least 70% then mismatching words will be underlined) | Re-record your paragraphs |
| ❌ Failed - Due to Speaker: | A mismatching speaker was detected between the consent and the paragraph | Re-record your paragraphs with the correct speaker |
| ❌ Error | The sample validation service, is either unavailable or failed for some reason (recording can be re-submitted without re-recording) | Recording can be re-submitted without re-recording |
| ❌ Timeout | This will be when the UI does not receive a validation response within a minute, you can resolve this with the recording being re-submitted | Recording can be re-submitted without re-recording |
Perfect voice score
The Voice Score and the number of paragraphs in their various states (i.e not recorded, validated, processing, failed) can be found at the top of the page.
Make sure your voice score is as high as possible in order to maximise the quality of your custom voice.
