Playback of pre-recorded messages to respond to caller inquiries has been subject to delays inherent in speech retrieval. Latent periods, both initial and intra-message, are reduced by breaking speech elements (words, phrases, sentences, etc.) into opening fragments and remaining portions. For each pre-recorded speech element for a particular application, an opening fragment (e.g., 4K bytes of speech data) is stored in active computer memory. The remaining portion of each speech element, regardless of length, is stored in a large capacity speech storage facility. For an incoming call, an appropriate responsive message is determined. The opening fragment of a pre-recorded speech element for that message is retrieved from active memory and used to initiate message transmission to the caller. Contemporaneously, a remaining portion of the speech element is retrieved from the storage facility and moved to active memory. By concatenation techniques, the remaining portion is transmitted to provide continuous speech to the caller.
