“Research shows more than half of occupational voice users spend an average of 36.5 hours a week speaking, placing significant strain on their vocal cords.”
SINGLE SOURCE
One web search result quantifies occupational voice use for teachers (25-30 hours/week) and mentions cantors reporting 45 hours/week. While other sources discuss high voice use in professions, the specific figure of '36.5 hours a week' is not independently corroborated by a second source, although the general concept of high strain is supported.

“Before it can be widely rolled out, the team must complete validation and secure regulatory approvals and develop clear training guidelines.”
INSUFFICIENT EVIDENCE
No evidence was found in the provided web search results or cross-references to support the specific claim that the team must complete validation, secure regulatory approvals, and develop training guidelines before wide rollout. Although the need for validation (Claim 7) is supported, the specific procedural requirements listed here lack direct evidence.
