3. INTRODUCTION
1. It is a Real time Language Translator.
2. Which are capable of translating 40 different
languages
3. They were launched on October 4, 2017 by
Google
4. Google wireless headphones that connected
through Bluetooth

4. What is Google Pixel Buds…???
1. Pixel Buds are wireless Earbuds developed and marketed
by Google.
2. This allows the earbuds to translate conversations in real-
time.
3. The Pixel Buds look different from any other earbuds out
there.
4. They have a shallow hard plastic earbud and a bit of a cord
that's used to form a loop to keep the bud in your ear.
5. The earbud itself doesn't have the typical soft rubber tip
that goes deep in your ear, and that's actually a good thing.

5. Specifications
 To use the Pixel Buds need a Bluetooth enabled
Companion device
Android 5.0 or higher

8. How does it work?
Real-time speech translation consists of a chain of
several distinct technologies – each of which have
experienced rapid degrees of improvement over
recent years.

9. Input Conditioning
The Earbuds pick up background noise and interference,
effectively recording a mixture of the users' voice and other
sounds. "Denoising" removes background sounds
while a voice activity detector (VAD) is used to turn
the system on only when the correct person is
speaking (and not someone standing behind you in
a queue saying "OK Google" very loudly). Touch
control is used to improve the VAD accuracy

10. Language identification (LID):
This system uses machine learning to identify what language is
being spoken within a couple of seconds.
This is important because everything that follows is
language specific. For language identification,
phonetic characteristics alone are insufficient to
distinguish languages (languages pairs like
Ukrainian and Russian, Urdu and Hindi are virtually
identical in their units of sound, or "phonemes"), so
completely new acoustic representations had to be
developed

11. Automatic Speech Recognition (ASR):
ASR uses an acoustic model to convert the recorded speech
into a string of phonemes and then language
modelling is used to convert the phonetic
information into words. By using the rules of spoken
grammar, context, probability and a pronunciation
dictionary, ASR systems fill in gaps of missing
information and correct mistakenly recognised
phonemes to infer a textual representation of what
the speaker said.

12. Natural language processing:
NLP performs machine translation from one language to
another. This is not as simple as substituting nouns and
verbs, but includes decoding the meaning of the
input speech, and then re-encoding that meaning
as output speech in a different language - with all
the nounces and complexities that make second
languages so hard for us to learn.

13. Speech synthesis or text-to-speech (TTS):
Almost the opposite of ASR, this Synthesises natural
sounding speech from a string of words
or phonetic information.Older systems used additive
synthesis, which effectively meant joining together
lots of short recordings of someone speaking
different phonemes into the correct sequence. More
modern systems use complex statistical speech
models to recreate a natural sounding voice.

14. Putting it all Together
 Once ready to translate, the earbuds first record an utterance,
using a VAD to identify when the speech starts and ends.
 Background noise can be partially removed within the earbuds
themselves, or once the recording has been transferred
by Bluetooth to a smartphone.
 compressed to occupy a much smaller amount of data, then
conveyed over WiFi, 3G or 4G to Google's speech servers.
Google's servers, operating as a cloud, will accept the recording,
decompress it, and use LID technology to determine whether
the speech is in Chinese or in English.
 The speech will then be passed to an ASR system for Chinese,
then to an NLP machine translator setup to map from Chinese to English.
 The output of this will finally be sent to TTS software for English,
Producing a compressed recording of the output.
 This is sent back in the reverse direction to be replayed through the earbuds.

15. Features

19. When you open the box There is
a Indicator Light

20. Its have a USB Charger in the back
of the Box to charge the Pixel Buds
Its lasts about 4-5 Hours
There are two Golden Pin Sockets
(Right,Left) for Charging the Buds

21. Also There are two Golden tiny Pins

22. This Green LED Blinking Means that “Established the Connection Between
Android Device & Pixel Buds

23. CONCLUSION
Almost everything about the Google Pixel buds sounds really
interesting. Wireless headphones with a minimalist design, Google
Assistant and Google Translate integration, and a battery-equipped
charging case. Unfortunately, what is appealing on paper doesn't
work in execution here, with uncomfortable earpieces, a lack of high
frequency sculpting, and awkward, redundant voice assistant and
translation features. None of the smart, unique aspects of the Pixel
Buds work well enough to justify using them over just using the same
apps on your Android phone, and their audio performance falls well.
