Note
Often a reporting verb, used like said for a reply that repeats the speaker: "'Nor I,' echoed Sydney," in Richard Marsh's The Beetle (1897). In journalism the passive marks agreement, as with views that 'were echoed by The Economist'. Echoing someone need not be word for word. One can echo a point of view simply by sharing it.

Note
Here the echo runs across time rather than between people. An earlier thing finds its echo in a later one, as when 1960s frustration 'finds an echo in today's increasingly confrontational tactics' (Owen Shows, Gay Community News, 1991). The construction is shared with the 'sympathetic response' meaning. What differs is whether the answer comes from a person or from a later event.

Stevenson's 'kind, simple, and sincere speeches found an echo in his heart' is the classic shape. Here the echo is a response inside another person. That separates it from the 'calling back' meaning, where a later thing resembles an earlier one. Thomas Fuller's 'Fame is the echo of actions' (1642) shows an older, aphoristic use.
