	Pros & Cons from Real Users Pros I particularly like Synthesys. It has a good range of characters. Unlike many others, Synthesys has characters with wonderful movements. The avatars move by hand and their gestures are precise, the most real of all. The clothes of the characters are according to the work of each one. The Synthesys Panel is good and very easy, in addition to great-looking colors and backgrounds. It has the option to send Photos and replace the face of the avatar. Multiple languages supported in text to speech. Uploading the audio UPLOAD file is seamless and rendering is very fast. I believe they informed me that there will be updates soon and they are working on it. About the support, I have no complaints, on the contrary, I was well attended and very fast, with a lot of education and flexibility. Support Good. There were some good ai modules that allowed for the reproduction of text in a somewhat convincing manner. Synthesys is adding more resources and developing its product to help businesses grow in the new marketing arena. Cons I think they should invest a little in the sound, the rest is really good and I recommend it. The customer support is horrible, they are rude and unresponsive. The model barely updates, and no features worth mentioning. Needs more diversity. Racial and ethnic actors, and voices, are severely lacking.
