Voice to text - where the technology is (or isn't)

SCLS offers an after hours, on call phone number for urgent problems related to network down-time and serious response time issues.  All calls that go to voice mail are automatically converted to text.   As a recent example, one of the texts read as:

"So when you say router it's not about the Spa. so it's United Now I know you want me to pick up. I thought you said this. chocolate sauce to turn in alright."

How would you fix this problem?
