I recommend this FOCASEREC 64 GB Memory AI Voice Recorder with Speech to Text and Summarization Capability. The Voice Recorder comes with a USB-C charging cable and Instruction Manual. It has dual microphones with noise reduction that provides clear, precise voice recordings in varied environments.
I use the AI Recorder specifically for recording Lectures, I know it has the capability of recording both sides of conversation when you attach it to your phone but I do not use that functionality.
There is a dedicated Application and Lifetime Free AI Service with this package.
For Lectures the Summary and Key Points the AI provides for the recorded Lectures is incredibly precise and the Speech to Text is relatively error free. Access to the Recorder is Password protected for Privacy and Security and your files are assigned a Time Stamp and File Names.
I work with the AI Recorder on a PC that is Local and not connected to the Internet to protect my Privacy and it provides an additional layer of Security for my own piece of mind, as I do not fully trust AI at this time.
The AI recorder works with 104 Languages but does not Translate them.
The FOCASEREC AI Recorder is incredible technology and makes my study time more efficient and it serves as an AI Organization Assistant. The Files are easy to work with transferring from Recorder to my PC. It has helped to refocus my concentration on the valuable information in all of the Lectures and Meetings I attend.
