3 styles of speaking in English - "Greenhouse", "Garden", "Jungle" - Richard Cauldwell "A Sylabus For Listening Decoding
(...)
1. The Greenhouse – the domain of citation forms.
The citation form of a word is the soundshape spoken in isolation without any contact with other words. It is the form given in the pronunciation key of a dictionary. The word is preceded and followed by a pause and every segment and syllable is carefully articulated. These citation forms of words are like plants in a greenhouse which are kept in separate pots so that they can get strong early growth without any competitive contact with other plants. Greenhouse soundshapes are rare in spontaneous speech. They most commonly occur as answers to the question ‘How do I pronounce this word?’ and ‘What is the correct way to say this word?’

2. The Garden – the domain of the rules of connected speech.
The Garden domain is home to words-in-phrases-and-sentences and the rules of connected speech, which describe how the edges of words change when they come into contact with other words – for example did it becomes did‿it. In a garden, plants occur in pleasing arrangements, with agreeable contrasts of plant types, colours and scents. Similarly, there is genteel contact between the soundshapes of words, which are described in the ELT rules of linking, assimilation and elision. The sound substance of the Garden is orderly and describable in terms of rules and it has a faithful relationship with the sight substance of language: units of speech and units of grammar line up alongside each other nicely; pauses occur at phrase and sentence ends; declarative sentences end in falling tones and the nuclear stress occurs on the last lexical item in the sentence. Garden soundshapes are usually found in the acted speech of ELT materials, and may also be found in slow and medium-slow stretches of spontaneous speech.

3. The Jungle – the domain of unruly messy speech.
The Jungle is the domain of fast, unruly and messy speech. It is home to the realities of spontaneous speech where words are crushed out of shape. In the sound substance of the Jungle it is difficult, if not impossible to determine where one word starts and another begins. In fact it is often difficult to hear whether a syllable or word has occurred at all. The Jungle is a domain of extreme speeds and huge variations in clarity – a domain which is truly messy and unruly. Pauses can occur anywhere, falling tones occur at non-ends of sentences which may have the nuclear tone anywhere and sentences (if they occur at all) may end with a level or rising tone, whatever their grammar or function. But the biggest issue is that words and groups of words are mushed together into soundshapes which are very different to their Greenhouse and Garden soundshapes. Jungle soundshapes can be found in all spontaneous speech and they can even occur in scripted speech when it is not being spoken at extra-slow, careful speeds. (...)
