The /v/ sound is spelled with <v>, <ve> or <vv> in savvy. The /r/ sound is spelled <r>, <rr> or <wr> in wry.
The /v/ sound is a voiced labio-dental fricative. The /r/ sound is normally described as a voiced frictionless continuant or liquid. It has many allophones in RP, including a voiced continuant with grooved or retroflex tongue position before vowels, a single tap resembling /d/ intervocalically, and a voiceless fricative after /t/. The contrast can only occur initially or medially and is not generally a problem for foreign learners, but some speakers, including native speakers, may have a problem when it occurs medially if they also make r/w substitutions.
