Question

Apply these speaking strategies below when speaking:

• Relax.
• Enunciate vowels (a-e-i-o-u) more than in English.
• Don’t be afraid to mimic native speakers—it’s respectful
• Don’t rush yourself; rapid-fire speaking ability takes time.
• Think in wholes, and then put the parts together.
• Self-correcting while in the midst of speaking is ok.
• Pronunciation Tip: Say each syllable of a word going backward starting from the last syllable, and then say the word altogether aloud.

• Use a clear and audible voice even in private study.
• The Spanish V sounds like a B—put your lips together.
• The Spanish Z sounds like a S.
• The J sounds like an H.
• Do your best with the trilled RR—show effort.
• If a word ends in a vowel, n or s, stress the next to last syllable: Ca-ba-llo

Answer 1

The Spanish Z sounds like a S.

Not in most parts of Spain, where it sounds like an English TH in "thin".

The J sounds like an H.

Not quite. It changes from region to region, but the most standard one is not like an English H.

The rest sounds reasonable.
