"Respondings" is not a correct spelling in English, as the suffix "-ings" cannot be added to the verb "respond" which has a regular -s form in the present tense. The correct spelling should be "responses" /rɪˈspɒnsɪz/ with stress on the second syllable. It is also important to note that the suffix "-ing" can be added to "respond" to create the present participle "responding" /rɪˈspɒndɪŋ/ with stress on the first syllable.
