The Race's Language in Worldwar (Temporary Title)

Worldwar is a book series in which humans are attacked by aliens called the Race. The Race's Language is the official language of the Race and its empire. Somebody asked me what I thought the phonology and grammar of this language would look like, so I will answer them.

Vocabulary
This vocabulary consists entirely of loans into English, or loans which I will assume are filtered through the ears of English speakers. I have made the executive decision of giving them a fake "normalized form" consisting of the sound I would expect if that syllable was stressed in the word. This is because if I don't do that, many distinctions will go away, which is not a viable option for me.

Facts

 * The Race's language is canonically not able to be correctly pronounced by humans.
 * This implies an IPA chart is canonically counterproductive.
 * There are descriptions of the way that the Race's language sounds.
 * To human ears, the dominant sounds of the Race's pronunciation are hisses and pops, as well as clicking noises.
 * To the Race's ears, human pronunciation will inevitably sound mushy to Lizards and those who have heard them articulate their language.

Strategy
I am not very well-versed in the book. I will assume that all of the loans are loans into English and get that out of the way.

My basic strategy is to go syllable-by-syllable through the loans, parsing syllables as I (a native English speaker) would, then trying to accentuate all hissing, clicking, and popping in each syllable.

My general assumption is:
 * the vowel sound is accentuated with formants to the point that they sound like hissing.
