1
00:00:13,248 --> 00:00:15,376
This is Unit 3B

2
00:00:15,988 --> 00:00:18,696
Easy-to-understand
and audio description

3
00:00:19,391 --> 00:00:22,632
element 3, Technical aspects

4
00:00:23,634 --> 00:00:25,442
video lecture, Voicing.

5
00:00:27,319 --> 00:00:31,394
I am Luis Alonso-Bacigalupe,
from Universidade de Vigo, Spain

6
00:00:32,259 --> 00:00:34,421
and in this short video lecture

7
00:00:34,836 --> 00:00:38,026
created by my colleague
Lourdes Lorenzo-García

8
00:00:38,569 --> 00:00:40,867
I will give you an overview

9
00:00:41,399 --> 00:00:44,759
of the main software
used to prepare voicing

10
00:00:45,170 --> 00:00:47,622
taking into account its importance

11
00:00:47,990 --> 00:00:52,511
when considering blind people
with cognitive disability.

12
00:00:55,627 --> 00:00:58,533
In the European project ADLAB PRO

13
00:00:58,936 --> 00:01:02,526
Nina Reviers,
from the University of Antwerp

14
00:01:03,057 --> 00:01:06,892
stressed the importance of voicing
for audio description:

15
00:01:07,914 --> 00:01:10,759
the so-called
para-linguistic information

16
00:01:11,370 --> 00:01:14,095
can have a great influence
on meaning.

17
00:01:16,224 --> 00:01:20,693
When considering blind people
with some cognitive disability

18
00:01:21,537 --> 00:01:25,870
voicing and the principles
related to "listenability"

19
00:01:26,507 --> 00:01:28,681
must be carefully attended.

20
00:01:31,059 --> 00:01:33,928
There are
different professional programmes

21
00:01:34,150 --> 00:01:36,681
to prepare voicing
for audio description:

22
00:01:38,005 --> 00:01:42,388
Pro Tools, Logic Pro, Cockos Reaper

23
00:01:42,828 --> 00:01:47,121
Adobe Audition, WavePad, FL Studio

24
00:01:47,673 --> 00:01:51,680
Sound Forge Audio
or Noblurway Mosaic.

25
00:01:54,202 --> 00:01:57,397
You can also use free software

26
00:01:57,926 --> 00:02:01,744
such as Audacity, Ardour,
Free Sound Recorder

27
00:02:02,322 --> 00:02:07,046
AVS Audio Recorder (for PC)
or Garage Band

28
00:02:07,584 --> 00:02:10,787
Quick Time or Ocean Audio (for Mac).

29
00:02:12,373 --> 00:02:15,438
They incorporate basic plugins

30
00:02:16,074 --> 00:02:18,144
(EQ-Compressors, etc.)

31
00:02:18,516 --> 00:02:20,945
which can be of use when recording.

32
00:02:24,341 --> 00:02:28,232
In Spain, the app AudescMobile

33
00:02:28,457 --> 00:02:32,109
was developed by S-Dos, CTI

34
00:02:32,815 --> 00:02:35,682
ONCE and Fundación Vodafone España.

35
00:02:37,012 --> 00:02:38,919
It is a free app

36
00:02:39,169 --> 00:02:42,080
which can be installed
in mobile phones

37
00:02:42,349 --> 00:02:46,428
as well as in iOS
and Android-system tablets

38
00:02:47,179 --> 00:02:50,190
and allows blind people
to have access

39
00:02:50,401 --> 00:02:53,663
to audio-described films
and TV-series.

40
00:02:55,628 --> 00:03:00,531
However, users refer
some synchronization problems.

41
00:03:02,933 --> 00:03:04,716
Moreover, ISTRAD

42
00:03:05,385 --> 00:03:09,610
Instituto Superior
de Estudios Lingüísticos y Traducción

43
00:03:10,008 --> 00:03:12,484
has developed TrAD-Software

44
00:03:12,663 --> 00:03:14,981
a programme which can be used

45
00:03:15,311 --> 00:03:18,276
both to write audio-described texts

46
00:03:18,532 --> 00:03:22,035
and to record
the audio-descriptor's voice.

47
00:03:24,852 --> 00:03:29,890
Here you can see
the interface of Noblurway Mosaic

48
00:03:30,363 --> 00:03:32,040
just as an example.

49
00:03:34,851 --> 00:03:38,413
The appearance
of a digital rythmo band

50
00:03:38,808 --> 00:03:43,616
allows to perfectly synchronize
dialogues and audio description lines.

51
00:03:45,765 --> 00:03:48,325
As far as audio description
is concerned

52
00:03:48,758 --> 00:03:53,663
the band will mark silences
rather than speech fragments.

53
00:03:54,999 --> 00:03:58,845
The audio-descriptor
(one or two, in this software)

54
00:03:59,352 --> 00:04:03,856
quickly identifies each silence
(possible areas of writing)

55
00:04:04,151 --> 00:04:06,062
where they can add a comment

56
00:04:06,458 --> 00:04:09,962
as there is no dialogue,
no noise, no music.

57
00:04:12,527 --> 00:04:14,465
During the recording session

58
00:04:14,699 --> 00:04:18,769
the actor starts to read
each audio description line

59
00:04:19,280 --> 00:04:22,405
as soon as they see
the plain line (silence).

60
00:04:23,367 --> 00:04:27,182
Moreover, they can also
see the notes (if any)

61
00:04:27,487 --> 00:04:32,521
included by the audio descriptor
in an additional text track

62
00:04:32,752 --> 00:04:37,728
(information about the performance
of the actor or actress).

63
00:04:39,423 --> 00:04:41,995
Here you can find an example.

64
00:04:45,583 --> 00:04:48,541
Each audio description line
can be stretched

65
00:04:48,980 --> 00:04:51,119
to take up the available space.

66
00:04:52,616 --> 00:04:55,281
Unlike methods using a paper script

67
00:04:55,487 --> 00:04:59,704
it is not necessary to note
the timecode of the lines

68
00:05:00,036 --> 00:05:04,361
since it is automatically assigned
when entering the text.

69
00:05:06,571 --> 00:05:10,312
If required, the text
of the audio description lines

70
00:05:10,512 --> 00:05:15,880
can be exported in a document
with timecodes and notes of writing.

71
00:05:18,941 --> 00:05:21,447
In order to publish
audio descriptions

72
00:05:21,847 --> 00:05:25,028
you can use
different download formats.

73
00:05:25,428 --> 00:05:27,401
Some of them are text based

74
00:05:27,601 --> 00:05:30,624
whilst some others are media based.

75
00:05:33,303 --> 00:05:34,833
Text-based formats.

76
00:05:35,633 --> 00:05:39,012
These can be downloaded as a WebVTT

77
00:05:39,712 --> 00:05:44,216
TXT, DOC, Merged TXT, Merged DOC

78
00:05:44,916 --> 00:05:48,377
Stamped Doc, and Merged Doc (Stamped).

79
00:05:50,875 --> 00:05:52,363
Media-based formats.

80
00:05:52,763 --> 00:05:56,070
Audio description alone,
without the source audio.

81
00:05:56,470 --> 00:06:00,577
These can be downloaded
as an MP3, OGG or WAV.

82
00:06:02,535 --> 00:06:08,383
Audio description plus source media
plus captions combined into one file.

83
00:06:09,583 --> 00:06:14,866
These can be downloaded
as an MP4, MP3, OGG or WAV.

84
00:06:18,316 --> 00:06:21,668
Since most popular video players
and platforms

85
00:06:22,068 --> 00:06:25,405
do not support
WebVTT description tracks

86
00:06:25,805 --> 00:06:27,681
or secondary audio tracks

87
00:06:27,981 --> 00:06:29,814
for academic purposes

88
00:06:30,314 --> 00:06:32,416
you can use the 3Play Plugin.

89
00:06:33,773 --> 00:06:36,218
This plugin references the video

90
00:06:36,518 --> 00:06:40,761
and plays the secondary
audio description track along with it.

91
00:06:43,961 --> 00:06:46,677
The 3Play Plugin is a free tool.

92
00:06:47,677 --> 00:06:51,116
By using it,
you can create an accessible video.

93
00:06:52,703 --> 00:06:54,469
This plugin is compatible

94
00:06:54,669 --> 00:06:57,920
with most video players
and publishing platforms.

95
00:06:59,069 --> 00:07:03,607
It enables users to add captions
and audio description.

96
00:07:05,776 --> 00:07:09,438
You can give it a try
by accessing the link on the screen.

97
00:07:11,733 --> 00:07:12,740
Important!

98
00:07:13,640 --> 00:07:17,675
After voicing,
the audio must be carefully edited

99
00:07:18,562 --> 00:07:21,941
taking special care
to undesirable noises

100
00:07:22,141 --> 00:07:25,143
and paying attention
to the quality of sound

101
00:07:25,743 --> 00:07:30,035
that is, appropriate speech rate,
right tone, strategic pauses

102
00:07:30,235 --> 00:07:31,617
proper breathing...

103
00:07:34,424 --> 00:07:38,499
In the edition process,
file types and audio quality

104
00:07:39,407 --> 00:07:43,574
that is, bitrates, sample rates
and mono versus stereo

105
00:07:44,074 --> 00:07:45,998
must be taken into account

106
00:07:46,398 --> 00:07:48,981
and selected
according to type of media

107
00:07:49,281 --> 00:07:52,465
that is, films, TV series, web series…

108
00:07:54,884 --> 00:07:57,854
More information
about audio description

109
00:07:58,154 --> 00:08:00,908
types and what elements to transfer

110
00:08:01,108 --> 00:08:04,178
is provided in the video lecture
within this unit

111
00:08:04,922 --> 00:08:08,788
"The creation, adaptation
and validation

112
00:08:09,101 --> 00:08:12,562

and audio subtitling"
produced by Elisa Perego.

114
00:08:18,589 --> 00:08:23,176
The interviews with users
conducted by Ester Hedberg

115
00:08:23,876 --> 00:08:28,667
that is, "Audio description
and audio subtitling users voice

116
00:08:28,967 --> 00:08:32,270
on audio descripion,
audio subtitling Camilla"

117
00:08:32,670 --> 00:08:36,500
and "Audio description
and audio subtitling users voice

118
00:08:36,700 --> 00:08:39,884
on audio descripion,
audio subtitling Anna"

119
00:08:40,384 --> 00:08:44,917
are a must if you want to see
their needs first-hand.

120
00:08:46,340 --> 00:08:49,969
You can also have a look
at audio description guidelines

121
00:08:50,169 --> 00:08:52,473
on the link you can see on the screen

122
00:08:52,773 --> 00:08:57,096
to learn about the main aspects
of audio description voicing.

123
00:08:59,389 --> 00:09:03,783
