Some sound laws specifically operate only in pausa. For example, certain phonemes may be pronounced differently at the beginning or the end of a word if no other word precedes or follows within the same prosodic unit, as in the citation form. That is the case with the final-obstruent devoicing of German, Turkish, Russian, and other languages whose voiced obstruent consonants are devoiced pre-pausa and before voiceless consonants.
The opposite environment is relevant in Spanish; its voiced fricatives become stops post-pausa and after nasals. Such environments are often termed pre-pausal and post-pausal, respectively. The phrases in pausa and pausal form are often taken to mean at the end of a prosodic unit, in pre-pausal position, as pre-pausal effects are more common than post-pausal effects.
In English, the last stressed syllable before a pausa receives tonic stress, giving the illusion of a distinction between primary and secondary stress. In dialects of English with linking or intrusive R (a type of liaison), the r is not realized in pausa even if the following word begins in a vowel. Similarly, French liaison does not operate in pausa.
English words that have weak and strong forms are realized as strong after and often also before a pausa.
In Arabic, Biblical Hebrew, and other Semitic languages and in Egyptian, pausa affects grammatical inflections. In Arabic, short vowels, including those carrying case, are dropped before a pausa, and the gender is modified. The Arabic alphabet has a letter ة (tāʾ marbūṭa تاء مربوطة) for the feminine that is classically pronounced [h] in pausa but [t] in liaison. In Biblical Hebrew, /laχ/ (לָךְ) is the general feminine form of 'to you' but also the pausal masculine form.
In Spanish, voiced fricative/approximants [β̞, ð̞, ɣ̞, ʝ̞] are pronounced as stops [b, d, ɡ, ɟʝ] after a pausa, as well as after a nasal.
In Tuscan, the full infinitive form of the verb occurs only pre-pausa.
