Steps to reproduce:

• install the SAPI 5 variant of Code Factories Eloquence, the one for SAPI 5 and not the one with NVDA addon
• in NVDA select the voice
  Code Factory ETI Eloquence Deutsch

Actual behavior:

• • let Eloquence speak the sentense
    für viele Leute ist schluss
    you will hear
    ür viele leute ist schluss
    and when you use CTRL+arrow right you'll hear
    iele
    instead of
    viele.
    So the first character is missing.

It only happens with some characters like f, v and so on but not with the S or SCH of Schluss or the L of Leute.

Expected behavior:

Eloquence should speak
für
viele
without the first character missing
