伏翼（英语：Pipistrellus pipistrellus）在英国有两种语音类型，其回声定位叫声分为两个不同的频带，最大能量的平均频率为55 kHz和46 kHz。为了简单起见，这些在这里被称为55 kHz和45 kHz语音类型。雄性在交配季节产生的Songflight调用，可能是为了吸引女性，不同的两种声音类型的数量的组件中的调用和调用参数测量。55 kHz声音类型的鸣禽叫声通常由三个成分组成，其频率高于45 kHz声音类型的鸣禽叫声，通常由四个成分组成。个体之间的呼叫参数也存在显著差异。判别分析songflight呼叫分类100%的个人正确的语音类型。回声定位呼叫频率和鸣唱飞行呼叫频率之间的关系在不同的语音类型之间存在显著差异。在飞行过程中产生的社会呼叫也不同的声音类型，在组件和呼叫参数测量的数量。社会呼吁进行了比较，每一种语音类型的songflight呼叫。55 kHz的语音类型的社会调用没有显着不同songflight调用;有小，但显着差异的两种类型的45 kHz的语音类型的调用。本研究支持了音型应被视为兄弟种的假设。如果鸣唱的声音被用于择偶，这种差异可能会导致两种声音类型之间的生殖隔离。鸣唱呼叫和社会呼叫的功能需要通过实验研究来解释语音类型之间差异的含义。
The pipistrelle (Pipistrellus pipistrellus) occurs as two phonic types in Britain, its echolocation calls falling into two distinct frequency bands, with mean frequencies of maximum energy at 55 kHz and 46 kHz. These are termed the 55 kHz and 45 kHz phonic types here for simplicity. Songflight calls produced by males in the mating season, probably to attract females, differed between the two phonic types in the number of components in the calls and the call parameters measured. Songflight calls of the 55 kHz phonic type, which generally consisted of three components, were of higher frequencies than those of the 45 kHz phonic type, usually of four components. There were also significant differences in call parameters among individuals. A discriminant analysis of songflight calls classified 100% of individuals to the correct phonic type. The relationships between echolocation call frequency and songflight call frequency differed significantly between phonic types. Social calls produced during flight also differed between phonic types, in the number of components and call parameters measured. Social calls were compared to songflight calls of each phonic type. Social calls of the 55 kHz phonic type did not differ significantly from songflight calls; there were small but significant differences between the two types of calls of the 45 kHz phonic type. The study provides support for the hypothesis that the phonic types should be treated as sibling species. If songflight calls are used for mate choice, the differences may allow reproductive isolation between the two phonic types. The functions of songflight calls and social calls need to be investigated through experimental studies to explain the implications of the differences between phonic types.
