Reviewer notes 3 issues found
1
Hyphenation

"fourteen day" — should be "fourteen-day" (compound adjective). Without the hyphen, TTS reads it as two separate words instead of one unit. Sounds disjointed.

2
Brand pronunciation

"Nimbus" pronounced as "NIM-bus" (emphasis on first syllable) — brand is "nim-BUSS" (emphasis on second). Apply SSML pronunciation hint or re-record with explicit stress mark.

3
Pacing

No pause between "priority support" and "and our analytics" — sounds rushed. Add 150ms break. Also, "nimbus dot cloud slash start" needs SSML break tags for URL clarity.

OK
Tone

Professional tone consistent throughout. Volume levels normalised correctly.
