Unknown Bloomer for ID

[Voyagenation]

Hi, Can anyone help in giving the ID of this orchid?

It bloomed and its flowers open in the morning and start to close by the late afternoon. By evening, its totally closed.

Flowering period remains for over a month with the earlier blooms falling and the newer buds opening as the older flowers fall. There are still some buds on the stalk.

Got this is the Bicol region, particularly in Legaspi.
