Currently, there is still not too much fierce competition in TTS. Among all the ones that I tried, Read Aloud is the best. talkie is a half finished, product, speed adjustment is in the "coming soon" premium version, which I suppose is not free. Chirpy is a DOA. "Text to speech that brings productivity" is a godzilla for such an easy task. Firefox's own reader mode TTS is also a flop. In Japanese text, it skipped the dates and and was sluggish on words. Sentence sounds like a bag of words.

Read Aloud allows me to choose voices, such as the superior Google Japanese female voice that just rocks! She read through dates and English words in Japanese text like a local. "Macron" sounds more recognizable than any other TTS. Currently the go to TTS in my Firefox.
