In Japanese, the numeral+counter combinations show a few different kinds of irregularities in their pronunciation. Typical examples are picked up in Table 3.2. The initial segment /h/ of 本[hoN] or 分[huN] has become /b/ or /p/ according to the final segment of numerals: e.g., 1本[iqpoN], 2本[nihoN], 3本[saNboN], etc. In ichi+compounds, the mora obstruent appears when the initial segment of counter is /h/ or /k/: e.g., 1本[iqpoN], 1回[iqkai], 1分[iqpuN], etc[25].
