Arithmetic for Phones and Features

In [1]:

from phones import PhoneCollection
pc = PhoneCollection()

Phones in this library support arithmetic operations. Please note that this is fairly slow when not filtering by language and/or dialect.

In [2]:

(pc.phones("ø").val + pc.phones("o").val)[0]

Out[2]:

(1.0, eo (bhg))

PhoneFeatures¶

Using a PhoneFeature, individual features can be altered.

In [3]:

from phones.features import PhoneFeature

In [4]:

(pc.phones("ʉ").val + PhoneFeature("back", 1))[0]

Out[4]:

(0.0, ʉu (fao))

In [5]:

(pc.phones("ʉ").val - PhoneFeature("round", 1))[0]

Out[5]:

(1.0, ɨ̜ (kid))
