Thank you all for your feedback. My intention was to point out to importance of good pronunciation because both bad pronunciation and strong accent can bring problems in communicating.
I'm currently working on a new pronunciation app that I strongly believe will help ESL students dramatically improve their speaking skills.
I'd appreciate if you would check out the site saundz.com and tell me what you think and if you find it useful!
The app is coming soon and I would honestly like to hear your opinion about it once it launches.
