• Version 2: This is the current version. To cite this version specifically, use DOI 10.5281/zenodo.7997063. In this version we fixed some naming mistakes in the files (in 8 of the files the sentence was identified as t2 instead of s2), and added two missing stimuli (t5_neutral_t2_u04.wav and t5_sad_t1_u05.wav).
• Version 1: This was the initial version. To cite that version specifically, use DOI 10.5281/zenodo.3689710.

The EmoHI Test

The EmoHI Test was developed to measure the accuracy at which participants can recognize vocal emotions based on pseudospeech sentences that were produced in a happy, angry sad, or neutral manner. The EmoHI Test recordings are particularly suitable for testing hearing-impaired populations due to their high sound quality. All recordings, including the ones that were used in Nagels et al. (2020, PeerJ, doi: 10.7717/peerj.8773), are made available here.

The stimuli were recorded in an anechoic room at a sampling rate of 44.1 kHz. The microphone was placed at a distance of approximately 30 cm (12 in) from the speaker. The recordings were made by connecting a standing Røde NT1 microphone to a Presonus TubePre V2 preamplifier and a TASCAM DR-100 portable digital recorder. The gain of the recordings was adjusted for each emotion production using the preamplifier to record the stimuli at an intensity level that was approximately the same across emotions to reduce large intensity differences between the recordings of different emotions. The files are not RMS equalized.

Sound file name structure

The sound files are named using the following convention:

t[1-6]_{emotion}_s{1,2}_u[01-18].wav

• t[1-6] represents the talker who produced the stimulus: t1, t2, t3, t4, t5, or t6
• {emotion} is the label of the emotion that was produced: neutral, happy, angry, or sad
• s{1,2} is the pseudospeech sentence that was used: s1 for "Koun se mina lod belam." s2 for "Nekal ibam soud molen."
• u[01-18] is the utterance number: Number ranging from u01 to u18

For instance, t1_happy_s2_u01.wav is utterance 1 of talker t1 producing emotion "happy" using sentence 2.
