Sentence examples for ratio of speech from inspiring English sources

Due to LE the signal to noise ratio of speech increases, but at the same time the loudness, pitch and duration of phonemes changes.

We have proposed a new approach to measure the reverberation ratio for assessment of the acoustic signal quality and mainly for a blind estimation of the direct-to-reverberation ratio of speech signals.

The main purpose of this step is to enlarge the ratio of speech frames to non-speech frames in magnitude spectra to reduce the noise effect, as discussed in Section 'Effect of additive noise to the linear and logarithmic magnitude spectrum of a speech signal'.

To reduce this effect and make it closer to real-world scenarios, 2-s silence was added before and after each utterance to simulate a typical telephone conversation [8, 15, 23] in which the ratio of speech to non-speech is almost 40% to 60%.

The test database used in the implementations was created to simulate typical conversational speech by inserting 2-s silence before and after each utterance from core TIMIT test corpus so that the ratio of speech to non-speech was almost 40% to 60%.

delta formant 4     6.6 Voicing ratio   Rate of speech-related 7.1 Phoneme rate   features         7.2 Word rate.

The SNRs were measured as ratios of speech power and noise power, ignoring the frequency components below 300 Hz.

The speech cancellation (SCINT) was therefore calculated as the ratio of the speech signal output power to speech signal input power, frequency weighted and averaged in dB, similar to the intelligibility-weighted SNR calculation described above (10).

Table 2 Signal-to-noise ratio of narrowband speech Method SNR of narrowband speech   after G.711 decode (dB) Without watermark 36.92 LSB 31.58 Proposed 34.71.

Here, we use signal-to-noise ratio (SNR) of speech to evaluate the modified watermark method, whose results are shown in Table 2.

and represents the expectation of the ratio of a speech frame (frame p) to a non-speech frame (frame q) in the magnitude spectrum for the k th frequency bin.
