![]() Zoom was also selected as (1) participants do not need to have a personal account to join a Zoom meeting, which may be relevant for data protection obligations (2) the built-in recording function in Zoom allows local recording without relying on an internet connection. Zoom has been successfully used for supervised online data collection ( Leemann et al., 2020) and so may be a convenient recording tool already in use in remote data collection. They are a convenient way to record lossless format files, which are recorded by H6, and are used as standard in acoustic research. Phone-based options have the benefit of only requiring a smartphone to use, which most people have ready access to. We investigated these two options because they are convenient, free, readily available, and allow for local file storage. We add to this line of research, by comparing recordings made with a high-quality digital recorder, the Zoom H6 Handy Recorder (henceforth, H6) with recordings made using two “remote” options: the Zoom cloud meeting application (henceforth, Zoom) and mobile phone applications that produce sound files in lossless formats (henceforth, Phone). Noise, on the other hand, can, instead, lead to greater vowel space distortion in male voices ( De Decker, 2016). Second, lossy formats distort the F1-F2 vowel space in unpredictable ways both expansion and compression (i.e., changes in both F1 and F2 simultaneously) are observed inconsistently across speakers ( Bulgin et al., 2010) with women's speech showing greater distortion in lossy files recorded in quiet conditions ( De Decker and Nycz, 2011). First, F0 is often unaffected by the recording device and file format ( Bulgin et al., 2010 Fuchs and Maxwell, 2016 Jannetts et al., 2019 Maryn et al., 2017), although it is unclear whether this applies equally as well to F0 that exhibits significant dynamic changes as it does to steady F0 (which is what is typically tested). ![]() Two key findings emerge from these studies. mp3 files ( Bulgin et al., 2010), and audio extracted from compressed video files ( De Decker and Nycz, 2011). m4a files ( De Decker and Nycz, 2011), lossy compressed. Other studies have examined the effects of different file formats, such as lossless Apple. Research has already examined the performance of several devices that can be used for recordings such as iPads ( De Decker, 2016 Maryn et al., 2017), computers ( De Decker and Nycz, 2011 Kojima et al., 2019 Vogel et al., 2014), and smart phones ( Grillo et al., 2016 Kojima et al., 2019 Manfredi et al., 2017 Uloza et al., 2015 Vogel et al., 2014 see Jannetts et al., 2019, for a review). More generally, researchers may have to conduct recordings remotely for other reasons, for instance, because of ethical, political, or financial restrictions that make travel difficult or impossible. We note that these findings are of interest to phoneticians working on speech production even if COVID-19-related restrictions are completely lifted in some countries as researchers may continue to have limited access to speech communities in some countries. To adapt to the situation, we set out to test whether alternatives easily accessible to participants recorded remotely can produce recordings suitable for acoustic analysis. In perspective views, only objects on the target plane will be displayed full scale in parallel views objects on any plane perpendicular to the camera axis are displayed full scale.Speech production studies have been significantly impacted by the restrictions related to COVID-19 as both access to laboratories and face-to-face interaction with study participants have been restricted. The command must be calibrated for this command to work properly. Zooms the active viewport so that the view is full scale. This is particularly useful in perspective views. When you rotate a view after Zoom Target, the scene will rotate about the target. Zooms the view by specifying a target and window.Ī rectangular window forms to define the zoom with the target as the view center. Zooms the view to show all selected objects. Values greater than 1 zoom in values between 0 and 1 zoom out. Zooms the view in or out the specified amount.
