In one arrangement, information useful in understanding the content of user speech (e.g., phonemes identified by a speech recognition algorithm, data indicating the gender of the speaker, etc.) is determined at an apparatus (e.g., a cell phone), and accompanies speech data sent from that apparatus. (Steganographic encoding of the speech data can be employed to convey this information.) A receiving device can use this accompanying information to better understand the content of the speech. A great variety of other features and arrangements-some dealing with imagery rather than audio-are also detailed.
