Audio processing and ALC in the FT-897D. I recently bought an FT-897D, and after a period of operation noticed. problems with what I perceived to be a low average level of output power and. reports of muffled audio. This is the story of my investigation to improve the. audio quality and increase the average level of transmitted power.
Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel. For example, English suffix-s is pronounced [s] when it follows a voiceless phoneme (cats), and [z] when it follows a voiced phoneme (dogs).
Some consonant sounds are voiced and some are voiceless. A voiceless sound is one that just uses air to make the sound and not the voice. You can tell if a sound is voiced or not by putting your hand gently on your throat. When you say a sound, if you can feel a vibration it is a voiced sound. Voicing is important because sometimes it's the only difference in the pronunciation of two very different words, such as 'bet' and 'pet'. Bet /bet/ - the /b/ sound is voiced. Pet /pet/ - the /p/ sound is voiceless. Sorry, you can't see the video for this topic :-(. However, you can download it to play on your computer.
