What happened and what to do
The Artificial Analysis report places HeyGen Voice first in the Controlled Voice TTS Arena, with an Elo of 1,201 across tests with 8 cloned voices in US and UK English. The model finished ahead of competing commercial speech synthesis models. The independent comparison also evaluates quality, pronunciation, price per character and speed across the listed models.
For a company, the case shows why voice models should be measured against its own criteria before choosing a supplier. A useful practice is an internal evaluation pipeline: a set of real business texts, authorized voice samples, automated runs of candidate models, and a dashboard covering pronunciation, latency and cost per character. This environment can run on the client's infrastructure, keeping texts and voices under its own control.
How the consultancy can help
Diagnosis of the company's voice use cases and design of an internal evaluation pipeline for speech synthesis models, with metrics for pronunciation, speed and cost per character, implemented on the client's infrastructure.
