Does any canonical sutta say you can attain enlightenment *while* chanting?

Bhante Saddhasara (of Sunshine Meditation Center, Florida) came through with the answer: in the Aṅguttara Nikāya The Book of the Fives, Sutta 26, “Liberation”, the “five bases of liberation” are listed.

Number three is “Reciting the Dhamma”. The pali term for “Reciting” is “sajjhāyaṃ karoti”, which can also be translated as “chanting”, however the chanting referred to here must be deeply understood by the one chanting. That is to say, the type of chanting here is not as in incanting a mystical, magical spell in an arcane language, where you don’t know what the words mean, where the power is inherent to the sound of the words. It’s not like “Abra Cadabra.”

This means you can only possibly attain enlightenment if you are chanting in your mother tongue, or in a language you are fluent-enough in, such that you can reflect deeply on the meaning, as you say the words. It’s the meaning of the words being felt and understood deeply which trigger the joy, etc.

…he recites the Dhamma in detail as he has heard it and learned it. In
whatever way the bhikkhu recites the Dhamma in detail as he has heard it
and learned it, in just that way, in relation to that Dhamma, he
experiences inspiration in the meaning and inspiration in the Dhamma. As
he does so, joy arises in him. When he is joyful, rapture arises. For
one with a rapturous mind, the body becomes tranquil. One tranquil in
body feels pleasure. For one feeling pleasure, the mind becomes
concentrated. This is the third basis of liberation, by means of which,
if a bhikkhu dwells heedful, ardent, and resolute, his unliberated mind
is liberated, his undestroyed taints are utterly destroyed, and he
reaches the as-yet-unreached unsurpassed security from bondage.
