Text-to-speech moved past demo voices. The hard part now is shipping audio that stays clear across numbers, brand names, and short UI style lines. This roundup tests five text-to-speech APIs on Wiro with the same support script, plus a quick Turkish sample where it makes sense.
Each model link is included below. All audio players use WordPress-hosted files.
Test setup
- English script (all models): Hi, thanks for calling Wiro support. Your refund is approved. You will see it in 3 to 5 business days.
- Turkish script (2 models): Merhaba, Wiro destek hattina hos geldiniz. Iadeniz onaylandi. Uc ile bes is gunu icinde hesabinizda gorunecek.
- One run per model per script (no retries)
