What is your source or personal experience for that? I don't think the typing system has any correlation. In fact you can actually type pretty fast with modern keyboard software, there are lots of shortcuts. I type in Chinese with friends and family everyday and so do my kids. Hardly anyone uses voice messages. I find leaving voice messages on messaging systems more popular with Spanish speakers than Chinese speakers, and Spanish is one of the easy languages to write for native speakers.
