Spoken Word Test

This page a bunch of random text thrown together while developing to test and demonstrate the functionality. Some of the content is copied from the Wikipedia article on “Bison”. For best results, also have installed a Spanish voice via your system's speech preferences. This test shows that speech can switch between languages. It also shows that controls are dynamically added when new articles are added to the document.

The functionality is disabled on Android and iOS devices because speechSynthesis is not implemented well enough on those platforms or there are issues with range selection on touch devices (you can force it on). So please test the following on Chrome, Firefox, or Safari on a desktop device (tested on OSX).


Let me tell you sobre mi animal favorito.

Great Creature

¡Este animal me gusta mucho!

Bison super-interesting and 'twas grandes are.

The Bison are—please take my word for it—very super-interesting, “and” y ¿por qué? they are even-toed ungulates in the genus Bisonwikipedia within the subfamily Bovinae.

Two extant and six extinct species are recognised. Of the six extinct species, five went extinct in the Quaternary extinction event. Bison palaeosinensis evolved in the Early Pleistocene in South Asia, and was the evolutionary ancestor of B. priscus (steppe bison), which was the ancestor of all other Bison species. From 2 MYA to 6,000 BC, steppe bison ranged across the mammoth steppe, inhabiting Europe and northern Asia with B. schoetensacki (woodland bison), and North America with B. antiquus, B. latifrons, and B. occidentalis. The last species to go extinct, B. occidentalis, was succeeded at 3,000 BC by B. bison.

Of the two surviving species, the American bison, B. bison, found only in North America, is the more numerous. Although commonly known as a buffalo in the United States and occasionally in Canada[1], it is only distantly related to the true buffalo. The North American species is composed of two subspecies, the Plains bison, B. b. bison, and the Wood bison, B. b. athabascae, which is the namesake of Wood Buffalo National Park in Canada. A third subspecies, the Eastern Woodland Bison (B. b. pennsylvanicus) is no longer considered a valid taxon, being a junior synonym of B. b. bison.[2] References to "Woods Bison" or "Wood Bison" from the eastern United States confusingly refer to this subspecies, not B. b. athabascae, which was not found in the region. The European bison, B. bonasus, or wisent, is found in Europe and the Caucasus, reintroduced after being extinct in the wild.

¡Este añimal me gusta mucho!

Reasons for awesomeness:

  1. Powerful and imposing
  2. Hairy
  3. Surviving


While all bison species are classified in their own genus, they are sometimes bred with domestic cattle (genus Bos) and produce fertile offspring called beefalo or zubron.

I told him, ¡hola!

An amazing creature.
