You suspect schizophrenia but in order to receive that diagnosis, other symptoms would need to be present including delusions or disorganized speech, among others. In the absence of those other symptoms, schizophrenia seems unlikely, though possible.
Schizophrenia can cause hallucinations (the voices you are hearing would be classified as hallucinations) but other potential causes include: substance use, dementia, epilepsy, fever, middle or inner ear disease, narcolepsy, severe medical illness, sensory problems such as blindness or deafness, and in rare cases, migraines.
I would recommend consulting your primary care physician about your symptoms. He or she can assist you in determining what might be wrong. The sooner that you seek help, the sooner a diagnosis can be pinpointed. Please take care.
