 The Mbrola project is a collection of diphone voices for speech
 synthesis. They do not include any text-to-phoneme translation, so this
 must be done by another program. The Mbrola voices are cost-free but are

+To add new Mbrola voice entry for eSpeak NG you have to:
 
 1. add Mbrola voice definition file,
 2. add Mbrola phoneme translation file,
 
 ### 1. Add Mbrola voice definition file
 
-eSpeakNG's voice files for Mbrola voices are in `espeak-ng-data/voices/mb` folder.
+eSpeak NG's voice files for Mbrola voices are in `espeak-ng-data/voices/mb` folder.
 Voice definition file is in form `mb-xxN` and have to contain at least this line:
 `mbrola <voice> <translation>`, e.g.
 
 
 Where:
 * `en1` is the name of the Mbrola voice.
-* `en1_phtrans` is a translation file to convert between eSpeakNG phonemes and
+* `en1_phtrans` is a translation file to convert between eSpeak NG phonemes and

 Binary `xxN_phtrans` files are kept in `espeak-ng-data/mbrola_ph` folder

 Additionaly Mbrola voice definition file can have other optional parameters,

 ### 2. Add Mbrola phoneme translation file
