אורח חיים ר״וOrach Chayim 206

Se’if 1א׳

בֵּרַךְ עַל פֵּרוֹת הָאִילָן בּוֹרֵא פְּרִי הָאֲדָמָה, יָצָא; אֲבָל אִם בֵּרַךְ עַל פְּרִי הָאֲדָמָה בּוֹרֵא פְּרִי הָעֵץ, לֹא יָצָא; הִלְכָּךְ אִם הוּא מְסֻפָּק בִּפְרִי אִם הוּא פְּרִי עֵץ אוֹ פְּרִי הָאֲדָמָה, מְבָרֵךְ בּוֹרֵא פְּרִי הָאֲדָמָה. וְעַל הַכֹּל, אִם אָמַר שֶׁהַכֹּל, יָצָא וַאֲפִלּוּ עַל פַּת וְיַיִן.

If one blessed Creator of ground produce on tree produce, one has fulfilled one's obligation. If one blessed Creator of tree produce on ground produce, one has not fulfilled one's obligation. Therefore, if one is in doubt of the type of fruit - whether it is tree produce or ground produce, one blesses Creator of ground produce. And, on everything, if one blessed Through Whose word everything was created, one has fulfilled one's obligation, even on bread or wine.

Se’if 2ב׳

הָיוּ לְפָנָיו פְּרִי הָאֲדָמָה וּפְרִי הָעֵץ, וּבֵרַךְ עַל פְּרִי הָאֲדָמָה וְנִתְכַּוֵּן לִפְטֹר אֶת פְּרִי הָעֵץ, יָצָא.

If there were before him a fruit of the ground and a fruit of the tree, and he blessed over the fruit of the ground and intended to exempt the fruit of the tree, he has fulfilled his obligation.

Se’if 3ג׳

כָּל אֵלּוּ הַבְּרָכוֹת צָרִיךְ שֶׁלֹּא יַפְסִיק בֵּין בְּרָכָה לַאֲכִילָה. הַגָּה: יוֹתֵר מִכְּדֵי דִּבּוּר (בֵּית יוֹסֵף בְּשֵׁם שִׁבּוֹלֵי לֶקֶט); וְצָרִיךְ לְהַשְׁמִיעַ לְאָזְנָיו, וְאִם לֹא הִשְׁמִיעַ, יָצָא וּבִלְבַד שֶׁיּוֹצִיא בִּשְׂפָתָיו; וְנֶאֱמָרִים בְּכָל לָשׁוֹן; וְלֹא יְבָרֵךְ עָרֹם, עַד שֶׁיְּכַסֶה עֶרְוָתוֹ; בַּמֶּה דְּבָרִים אֲמוּרִים, בְּאִישׁ. אֲבָל אִשָּׁה יוֹשֶׁבֶת וּפָנֶיהָ שֶׁל מַטָּה טוּחוֹת בַּקַּרְקַע, כִּי בָּזֶה מִתְכַּסָה עֶרְוָתָהּ וְעַיֵּן לְעֵיל סִימָן ע"ד סָעִיף ד'; וַאֲפִלּוּ אִם אֵינוֹ עָרֹם, אִם לִבּוֹ רוֹאֶה אֶת הָעֶרְוָה אוֹ שֶׁרֹאשׁוֹ מְגֻלֶּה, אָסוּר לְבָרֵךְ.

All of these blessings [on food and beverages] need to not interrupt between blessing and eating (or drinking), and one needs to make the blessing(s) audible; and if one does not make it audible, one has fulfilled one's obligation, as long as the words depart from one's lips. And the blessings can be spoken in any language. And one should not bless nakedly until one covers one's genitalia. What are speaking about? With a man. But, with a woman, she may sit with her lower genitalia being covered by the ground, since this covers her genitalia. And even if he is not naked, but if his heart does not see his genitalia or that his head is uncovered, it is forbidden for him to bless.
