Voice amplifiers are sometime the perfect moderate tech solution for learners who have soft or somewhat unclear voices. They can also be the prefect motivational tool for learner with low verbal abilities or help learners with hearing impairment with articulation. Here are some links to voice amplifiers:
- Chattervox (I have used this with many students)
- Voicewave Speech Enhancer (clarifies voice as well as amplifies)
- Luminaud (sells an assortment of voice amplifiers)
- Saltillo (sells an assortment of voice amplifiers)
Voicewave and Luminaud have funding advice/assistance.
One tip, get the behind-the-neck microphone it is the most comfortable and works the best.
