Cancatenated Sentence in Noise Hack 1.2.1 + Redeem Codes

Cancatenated sentence recognition in noise (10x5) test is to measure the user's ability to recognize sentences in the background noise using a closed-set approach. Five-word sentences are generated in real-time using cancatenation methods. Sentences with desired SNR will be presented and the user must choose the correct words. If the answer is correct, sentences with lower SNR will be presented. The lowest SNR that a person can recognize 50% of all trials is that person's sentence recognition threshold.
