…audio manipulation SPE has built-in basic audio files manipulation functionality, like separating individual channels from stereo recordings, cut one audio to several files, save audio from incoming stream to file and others. Stream audio player To support voicebot scenarios, SPE has the ability to play audiofiles directly to output RTP stream External Text-to-speech (TTS) integration Easy integration with external TTS…
…silence as well. The outputs of the technology can be both log files with labels and/or split audio files/one new multichannel audio file. Typical use cases: Preprocessing for other speech recognition technologies, labeling the parts of the utterance according to the speakers, splitting telephone conversations recorded in mono into several channels, identifying how many speakers are speaking in the recording….

Technology description Time Analysis Extraction (TAE) by Phonexia extracts base information from dialogue in a recording, providing essential knowledge about conversation flow. That makes easy to identify: long reaction time crosstalk responses of speakers in both channels speed of speech measured in phonemes per second Typical usage domain It is typically used in contact centers for indicating weak moments in…
…magically restore the information already lost during the original compression. No point trying that. 1 The joint-stereo encoding – which is commonly used by default in MP3 encoders – is tailored for usage with music audio, where both channels usually contain almost the same signal. Using joint-stereo encoding for telephony stereo, where each channel contains completely different signal (when one…
